3D design tips - precision hole placement in TinkerCAD and Onshape
Vložit

- In response to a viewers comment on TinkerCAD and having to guess placement of some parts.. I decided to do a tips video on precisely rotating some holes around a circular part. A little trick I came up with. (I'm sure there's many ways to do the same.)

Your video is a good example of how everyone benefits when someone shares some useful tips or tricks. Well done !
Wow. Great teaching video even 5 years later. I have been struggling to make a router base plate and get the holes aligned to the perfect dimensions in TinkerCad but your idea of creating a measuring stick is awesome and I will try that now. It's a 6" round plate with a 2 inch round hole in the middle (very similar to your GUY plate) with three holes for the M4 screws. The holes are 120, 120 and 110 apart so not exactly 120 degrees.. but should still be use this method...Thank you
Thanks, I'm sort of self taught and never realised how useful the alignment tools is - just learned a great deal off your video - cheers from UK
The alignment tool is huge! Tinkercad is an amazing program! If it just had a better way to measure it would be even more powerful!
Probably old news to you now but since this video there's now a shape generator available in TkCAD that will allow you to create a circular array of holes. Using it to get 3 holes aligned centrally with another cylinder seems hard work though! I found creating 8 holes, then aligning, then reducing it to 3 holes by simply moving the slider in the settings was the quickest way. Just look for "Circular Array" in Shape Generators to find it.
You seriously just saved me a good hour of extra work with this tip. Nice job, sir!!
Great tutorial. Discovered your channel thanks to the vlf ground antenna.
Personally i would duplicate 3 "holes" into the same place, make them diffrent heights so they can be selected individually. Make the first hole, rotate the washer 120 degrees and make the second one and so on - maybe this will save some time when making more than 3 holes :)
you dont need to make them seperate heights. You can just use whichever one you get when you click on them.
Superb video. Many thanks for sharing! Really helped me out. I had to create 5 holes 72 degrees apart (evenly spaced) and I managed it in no time. Thankyou!
Thumbs up for wanting to use the metric system and finding clever ways around Tinkercad! Nicely done!
Very clever. Got me thinking so I just rotated the disk 120 after making the first hole and it does the same. No measuring stick needed. Of course I made a copy of the hole that was left in the same place so I would be able to subtract it at the 120 rotation.
Just getting to do a few things with TinkerCad but have used CAD for my CNC milling machine a lot.
Fun leaning new things
Thanks a ton for this! I used to use SolidWorks back when someone else paid for it. Now that I have to use free stuff, it can be pretty challenging to make the free stuff do what was really easy in SolidWorks. This solved my problem in about 10 minutes.
Another EXCELLENT and practical tutorial Kevin. Thanks for sharing. Enjoyed how you did it in tinkercad but I won't be going back there ... really liking Onshape! 73 Dwight
About the only thing I still use tinkercad for is modifying existing STL files. Since it's a mesh based system, it imports them in an editable fashion. Example, I had a PLA printed replacement bushing for an LM8UU linear bearing I wanted to try. It's outer and inner diameter were just slightly off and it was too short for my printer. Those changes took a couple of minutes in tinkercad, where I would have had to redesign it from scratch in anything else.
But for scratch design, I'm totally digging OnShape.
spot on buddy, thanks for showing both platforms, i'll try onshape tmrw if its still available, thankyou
Thanks! I've been looking at a bracket I am designing and trying to figure out what you've just done in a couple of seconds!
Thanks for the tutorial. One suggestion to shorten the procedure a bit. If you want to move two or more items together, you don't need to group them before moving. Just select all of the objects using the shift key then the left mouse button to move them without having to group them first.
Thanks that was great, I learned a lot from this video. Definitely with you on going to the metric system.
Thanks.Implemented in my own project. Much appreciated.
Awesome tips. It helps with something I was trying to design
I use 'align' tool in TinkerCad a lot now -I understand they don't want to make it difficult to use and more features would probably do that but that pattern tool in Onshape has got me drooling!
Also in TinkerCad there is a shape almost at the end of the Shape Generators drop down (you have to scroll through a bit by hitting 'more shapes') that lets you do something like this automatically, its called 'circular array'. It has limitations on size though.
Tinkercad should make measuring better like in OnShape which I always use to do the measuring and then import into Tinkercad
I live in Canada and we use both system so. BTW love those tutorial, keep a it. Thanks from VE2TYG
Oui, De rien.
It's odd that this topic came up I've owned my 1st 3d printer for about a month an decided to learn the metric system everybody says it's the way to go and I will get it but being taught an using the standard for 50 years it's been tough on me but i think it will be better when i do get it down
The imperial system might be the standard here in the US, but nearly all of the rest of the world has gone to the metric system. It's hard to say it, but it really is true, that when it comes to weights and measures the US is the backwards third world country.
Ok. I was making duplicates of the measuring stick and the hole and the un grouping them and deleting. This makes it a bit easier and even more accurate.
I'm just a guy that needs to design a prototype for an invention that is just a round circle with 24 holes! I have no cad or drawing experience. TinkerCAD is a free product! For the Onshape, which you're right, has a great ability to quickly make all my holes, but paying $1500 for the software so it's easy to make 24 holes in a circle seems really steep to me!
Onshape is free for personal use.
@@loughkb Yeah, but they own everything you do so it's not good for someone looking to invent something to sell.
Thanks a bunch! Solved my 15mins of headache :D
Thanks for this Kevin, I needed to design several parts with holes that allowed countersinks for screw heads to fit flush. I was (w)racking my brains with Tinkercad on how to do this. Clearly OnShape is the way to go, so you've saved me some heartache. I think when people suggest beginners to 3D-printing should design on Tinkercad, I'm not sure that is right. Perhaps OnShape has a steeper learning curve, but perhaps a wiser investment of one's time in the long run?
Oh and here in the UK, I was a kid of the 60s & 70s when currency decimalisation came in. They also converted to teaching decimal measurements in primary school, so I was pretty adept at both but still visualise better in imperial for road distances and heights, whilst I always measure in decimal. Hate the old 3/16ths of an inch added to 5/8ths of an inch type malarkey.

I use both Tinkercad and OnShape but I'm much quicker at figuring how to do something in Tinkercad when in OnShape it is a lot more complicated. I try to do what I can in Tinkercad, export to OnShape for things that take precise measurement and such and then import back into Tinkercad. Tinkercad is an ingenious program and could be even more powerful with some good measuring tools such as OnShape has. The only thing I can think is that Autocad wants to keep Tinkercad crippled to force you to move into their paid programs.
nice video. great tip!
Muy buena la explicación, sencilla y práctica mas para principiantes que gustan reparar o modificar las cosas.
Awesome my friend
Clever! Now why didn't I think of that.
Keep up the great work, and good luck with future projects.

thanks for the info 👌
Thats all I use is Metric. Its gotten to a point stuff that we order online is mainly Metric. Not only that Metric in my opinion is so much easier to work with. I live in The USA myself
Yeah, I switched from Imperial to metric. It's just so much better for most things.
I quickly tried, and it took me 3 seconds in Sketchup but I'm used to this software. I dont have a 3D printer though, can you use sketchup in order to 3d print? I see all your videos, I'm itching to buy one now haha looks like so much fun!
As long as you can export the object as an .STL file, you can slice it for a 3D printer.
clever, thanks for this vid :)
Ha ha I got a surprise when your face appeared on the screen Kevin. I’m used to watching your radio videos de VK3AWA
If Tinkercad had a way to measure for holes and such it would be better than OnShape. It's super fast and intuitive.
It does in a way. There's a ruler function that you can lay down and then move your shape over the ruler to measure distance.
@@loughkb The ruler function might work but I could never get it to do what I needed done. Tinkercad is an ingenuous program and would be great if they could just add a few more abilities to it.
Hi Kevin i have been using Tinkercad and wanted something more powerful so after seeing this video I signed up for Onshape . Was wondering what you used to get up to speed on this software? Any good videos or books you recommend? thanks Bill N7OQ BTW I swear i know you from some where LOL. 73
It's so simple the whole book would only take one page!
metric works better than fractions.
Yeah, I use a measuring stick a lot but you've added some functionality with it. It shouldn't be hard for Tinkercad to make measuring really easy like in OnShape. I actually think Autocad wants Tinkercad to be crippled so they can get you into Fusion 360 easier.
Well as soon as they release fusion 360 for Linux, I'll be interested. Haha.
I think they really need to release a standalone version of tinker. That could be wildly popular with new 3D printer owners. If they priced it reasonable, 10 bucks or so. They would sell the heck out of it.
@@loughkb I would think even $89 it would sell like hotcakes! I mean, what other option for that kind of simple but powerful cad program is out there on the market? And if they charged for it maybe someone would come out with an improved Tinkercad! That would be awesome!
Wow, extremely complicated. The program I use to program my CNC Plasma Cutter allows one to draw an array. I can draw an object, place it where I want and then using the polar array option, tell the program to duplicate the object and space them exactly the same distance apart from a center point. For instance, I could draw a tooth for on a gear and specify how many teeth, I want evenly spaced around the circumference.
I was thinking as you designed. Wouldn't it be just as easy to just place a isosceles triangle centered on the flange and place hole at each point of the triangle?
Yes, except tinkercad wouldn't align on the corners. It alignes centered with respect to a rectangular area the shape occupies.
That's how I have done this kind of task in the past in OnShape.
Neat, same firmware version also. I've been printing away the last two days and currently printing the spool holder left side now. Almost thinking isn't worth the time since seems to be feeding OK with the stock holder. Any thoughts? I'm almost thinking going with the Y-axis extension to make the even larger X, Y and Z extension. I'm still looking around for 6mm stainless steel rods since appears the HP's officejets only have the 8mm for their carriage/sled. Might be some smaller ones... though not certain how they'll clean up having the rubber on them if even smooth and not recessed for. Had issues testing Cura on the Win7 Pro laptop... though tested the first time firing up with Pronterface (Printrun 2014.08.01) Printrin-Win-Slic2r-03Feb2015. Then installed Prusa3D and installed the same and some apps on the Win10Pro laptop and have been slicing in PrusaSlicer2.2.9 and printing with Pronterface since. Main issues I've found are my faults with attempting to splice the filament since I wasn't confident leaving the spool out even though the room humidity is only ~35%. Skip it now, I'm just letting er roll to see how performs and not repeating the only mistake I've found other than maybe using rectilinear infill and 0.3 resolution. Looks like the 0.1mm resolution is the way to go with this last print. Looks really smooth and solid. Star or Honeycomb seems to be OK... though maybe rectilinear at 100% infill is OK with the finer resolution of 0.1. Anyhow time to find free CAD apps and study those.
I didn't realize you have a few 3D printer videos and CAD videos. Will have to watch now. Only watched your antenna related videos for the most part. Thanks for sharing Kevin!
In Tinkercad, could you of used an 'equilateral triangle' as the "tool" instead of the 'measuring stick'? With a little math, I would think it possible to place a specifically sized triangle over your part, then center the 3 holes over each point of the triangle?...
I'm trying to learn TinkerCad, by thinking how I would attempt problems before the answer is giving in videos, and that was the first thought on how to do this. Admittedly, it would only work for a part requiring 3 holes where rotating the "measuring stick" could be used for any number of holes... Thanks, I love picking up new techniques!
Yeah, I think using a triangle would work for aligning three holes. There's probably several ways to do it. This is just one.
Nice tricks :-)
I would have done the big hole in the plate the same way, but then I would position the small hole where I wanted it , then select the plate and the small hole and duplicate them both and rotate the duplicates, and then dupe the duplicates and rotate those, and then delete the two extra plates. I did not know the neat tricks with the alignment tool. Is there a manual somewhere?
No manual, but many tutorial vids out there on both programs.
wow. Thanks a lot
Thanks 🙏 ser four help you 👍🏻👏🏻👏🏻👏🏻👏🏻👏🏻
Nice 👍🏻 ser thanks 🙏
Do you think Onshape is easier to learn than Fusion 360?
I just came across your channel and really enjoyed this tutorial + 1 Subs
I use onshape often and like it. I cant compare to fusion since I run linux on everything and they dont have a Linux version.
Onshape is a lot easier than Fusion 360, IMO. And a lot more intuitive.
nice one thx :)
Equilateral triangle is the shape you need.
Wouldn't it be easier to use a triangle that you know is equidistant along the horizontal planes and then mark that exactly in the center of the flange so that each of the three points are in the center of the flange?
That's how I would do it.
I'm sure there are many ways to accomplish the same.
Would you not want to have holes with less sharp edges? For fabric style rope, cordage. 73 kf4dcy.
Someone didn't watch the whole video. ;-)
That was the point of filleting the edges in the onshape version. I think I mentioned that.
I just started using tinkercad. and i had a faster way. and no need for the measuring stick.
Don't see the video on your channel off you explaining it?
im new on thias and this is an old video but i'snt more easy tu rotate the base on tinkercad?
Podría ser. Alguien más dijo eso
I'm pretty sure there is a specific tool called "array" to do this.
Why you dont use the ruler tool in thinkercad?
I do now. I hadn't discovered it back then.
Hello! If you go to Home Depot and ask for a 35 mm Pole they will laugh their butts off! LOL I was wondering about the strength and UV resistance of the plastic?
Yes, that's true. It's the sad state of things. Some day we'll catch up.
The strength is decent, it would come down to the design, thickness, and print direction. UV resistance depends on material used. PLA holds up pretty well, but doesn't like heat.
This vid was more about the technique than the sample part I built.
I made my guy wire rings out of square metal electrical outlet box covers that come with a hole in it in the center for the round recepticle that fits it. I drilled out the holes at each corner and a couple centered on two sides between holes on corners. That way I can guy it at three or four locations depending on wind load. I use one side hole on the guy ring to mount a pulley for a rope to winch my antenna center up once the poles are in the air.
The mistake you made with the holes is that you have calculated the edge to the hole edge! you should have calculated to hole center instead and you will get the hole centered perfectly :)
Couldn’t you have used a triangle and used the points as the center of the holes?
There's certainly several ways to accomplish the same result. This is just one.
Onshape looks good but I am not going to pay that price for something I will use occasionally.
You can use it for free.
it was good to hear an american voting for the decimal system, As a brit who used to have 240 odd pennies to our old pound i never understood why you don't use it when the very backbone of your currency is based on the metric system being 100 cents to 1 dollar.
It might have only taken us a year or so to make the change but nearly 50 years on people are still whining about pounds shillings and pence and talk about gallon of fuel! Even now in spain where I am nearly 15 plus years on they still talk about the peseta!
Have you seen the price for Onshape? 1500 usd per user..........who can afford that unless youre a designer on a self employed basis or something....its not a replacement for Tinkercad thats for sure. Unless I am looking at the wrong program?
It's free except for one caveat that OnShape owns all the 3D models you create and will publicly publish them. Not a big deal unless you are making things commercially to sell. Inventors would want to pay the steep yearly $1500 fee or go to Fusion 360 which is like half that per year.
English Measurements ..... NA .... more accuracy with metric and all electronics / Science measurements is in metrics ..... and yes I'm an American and a OLD ONE at that =) Interesting OnShape CAD ..... Tinker CAD .... Fusion 360 ...... what about Google Sketchup ???
There certainly is the ability for making parts with sketchup. Kind of like Blender, it's a tool designed for something else, that can be used for parts design as well. I'll have to give it another look. I think I read somewhere that it was moved into browser space, making it OS agnostic. The last time I looked at it, it was still windows and mac only.
I'm really digging OnShape though. I recently found out that they made their development language open source and available. You can actually program new features for use in OnShape now.
That is good you can add programming .... kind of like AUTOCAD MACRO's ???
More than that. It's the same framework and language the onshape developers use to write most of the built in features already in the program.
Pat Hopkins what is lead spacing on all IC's?
One clue it isn't metric..
2.54 millimeters. The standard spacing on DIP packages anyway. The JEDEC standards were proposed in 1944 and ratified in 1958. JEDEC was formed in the U.S., the leader (at the time) in integrated circuit design. They listed the spacing as 0.1 inches, obviously because that's the units of measure used here at that time.. However, you can use any unit of measurement you choose. 0.1 inches is 2.54 millimeters, or 0.00555556 cubits, or 1.3715e-6 nautical miles.
Most modern documentation lists DIP lead spacing in both inches and millimeters.
Good Video -- KE0FBB
Inches...
It's much easier to think and calculate mentally in a base 10 system.
Awesome, Onshape is only $20K
