If there is music in this video, it is legally used.
Note that you can achieve the same effect as applying a tangent relation between two edges, then a coincidence relation between the endpoints (e.g. as you do at 4:44 and 5:06) in a single step:
Simply select the two endpoints and apply a tangent relation (e.g. the toolbar button or the "T" key). This will create both a tangent relation between the lines and enforce coincidence between the points. Much easier!
I was just going to mention the same thing :)
Great Tutorial! Content, subject and execution. Didn't even realize I was watching for 30 minutes. Thanks!
Mee too
Very interesting! Thanks for sharing.
This was eye opening!!!!!
Very professional! 👍
Great and very easy tutorial. Thank you
Great content, thank you for sharing.
Impressive!
I played around with the grabcad model. I found that while using the surface tool in the surface workbench, you dont have to click "add edge" for every selection. If you click it once, you are allowed to then select your edges in the viewer in series. Also, I find I get wacky results when using edges that dont originate from the sketch, eg, the common sweep or other surfaces, however the different fill options "ccon" and "curve" did improve the shader normals somewhat
Nice video and work methods!
Muchas gracias, muy ilustrativo.
Super!
Thank you.
HI, I'm a FreeCad beginner (used to wok with Cinema4D). For the "Issue" with Mirror is quite easy to Solve.
Every time you Mirroring something, points on mirrored X or mirrored Y axis are overlaped (two on the same place instead of only one). It work more like a "COPY AND MIRROR". So the "FIRST EASY FIX" to do is select the "maybe double points on the X/Y Axis" with SelectionBox (if lines are selected, deselect them) and press C (Coincident Constrain). Overlaped points now are only beautiful one.
In Cinema4D is quite the same thing : just select with Selection Box points and press U-O (optimize). Overlapped Points are merged in 1 single point
Surface master!
Круто! С большим удовольствием посмотрел видео. Очень полезно.
Impressive
This was very cool. Thank you for the lesson.
Yes. I know already :D Thanks.
Coming from blender with its "select edge loop" which is done in single mouse click, this manual selection looks really tedious. Doesn't freecad has something similar?
Thankyou
love❤❤❤❤❤
Really useful! Thanks! Also pretty impressive what FreeCAD can offer when it comes to handling surfaces.
Would be nice to see if it's possible to add splines or "function driven" curves to the construction of the model. (I tried it with previous versions and couldn't find a solution for that. Maybe I overlooked the option mentioned somewhere..)
There are 2D splines in the sketch enviornment of course, you can also intersect and split surfaces for the equivalent of a '3d spline'. The curves workbench has similar functionality which I will be publishing content on soon.
@@JokoEngineeringhelp Thank you very much! Will check in practice.
Can you make a video on freecad modeling a car from 2d photos. Thanks.
Great tutorial! Do you have any plans to continue adding more detail, like cutting out buttons and hole for scroll wheel etc, and eventually turning it into something 3d printable?
I think I'm done with the mouse at this time, I do make a more detailed one in an older video
@@JokoEngineeringhelp So Solidworks has its weird bugs too?
@@j121212100 Indeed, perhaps not as much as the Creo guys accuse it of having though!
Someone should add a feature where we can create a spline in 3D space and can be constrained from any of the xy, xz, zy (probably in a projection type of method). Can be very competitive against the method of drawing 2 sketches and projecting it to form a single projected curve like in Solidworks.
Not quite close to the Fusion360 actually but I really like that FreeCAD is actually free and of course its Python possibilities. Python thing is very powerful.
The sweeping gave me so much trouble because I did not follow precisely step-by-step. It is so counter-intuitive. After like 10 tries I had no clue what was broken.
The thing that clicking "Done" does visually nothing and it gives no messages on what is up.....I had no clue that clicking OK was the only thing holding me back from creating an actual surface XD
The Part workbench is older and more tricky like that. I usually default to part design for the more modern and intuitive workflow.
I designed an object in part design and wanted to add a solid, made with the surface worbench, to the body. i dragged and droped the solid to the part design body. it created a base feature. un fortunaly i recieved an error. could it be, that i can only use this solid in the part workbench?
But will FreeCAD handle task where we want to smooth transition between top surface and all sides patch by fillet?
That would be amazing if possible!
Thank you, but I can not take the point in the mourse'surface to import in to sketch004(at 15:15). Can you let me know why?
Sometimes that happens on the wrong side of the sketch plane. Try turning your view 180 degrees
if you click on were it says degree of freedom it will show you were it is!
What degree of tangency is between surfaces? Can you control it? If you create plastic part, would the edges be visible as ridges? Or what about applying the zebra light(does FC even have it? I cannot find any video about it).
The zebra tool will be in the curves workbench- you may also find some additional surfacing tools for tangency in there as well.
@@JokoEngineeringhelp Well thanks. Will check it out..
60fps == smooth
Doing this surface directly here is nothing new. It's just a different method. If start from scanned data to facet then convert to CAD surfaces to match it, can you do it?
My approach would be to either delete bad elements and fill the empty spaces with my own if FreeCAD will allow or build surfaces based on the scanned model. I don't work with scanned data in FreeCAD though, so there may be someone who has that has some insight
Hi, great videos however I can't even get off from the starting line with Freecad on Win 8, version 18.4 won't open, version 19 is giving me strife over parts library, I've tried uninstalling and deleting folders and files and tried multiple attempts at reinstalling, version 19 seems to need Gitpython, and Python and just, getting confused,spent 3 days back and forths to get Freecad to work for starters then to work with Libraries, guess it's just me but bloody hell it's frustrating when your an old fart trying to keep up with the rest of the world, cheers.
Hi thanks for the comment, maybe I think I have found the problem,I have read that you need to clone the library rather than download the Zip file and place it in the Mod folder like the instructions say to so now have o learn how to Git Clone now....think my head will split open doing this... be nice to have a video explaining this most confusing set up, anyway sometime later I'll have a crack at doing this, cheers.
I have Win7/64 and use the .19 zip/portable version, no installation. Works a charm, very stable.
Hi there, Great video, however I have a problem creating a model, I wounder if you are able to help me with it, it's simple but I have not seen anything thing like it being created.
Cheers Neale
Do you have a link to an image?
Super annoying if you have to click add edge between every edge instead of going into a mode of adding edges.
This is the point - surfacing - where Freecad has way more capabilities like Alibre...
Can u please do it in alibre too?
Hi King,
Alibre doesn't have surfacing tools in the same way, so the mouse would need to be made with a solid loft or series of lofts
@@JokoEngineeringhelp do u think its possible? in a resoable time, or using a other programm like rhino first
Absolutely Shit Hot! Why not spline the arcs before creating the surfaces?
Why thank you. What would you mean by spline the arcs?
@@JokoEngineeringhelp Apologies for being so late in getting back to you! The shape of a mouse suggests it would have originally been drawn as a spline which is why I am wondering why you didn't trace the arcs?
imagine designing a mouse without a mouse.
Have tried FreeCAD a few times and each time I was struck by the awful fiddly design process. I finally settled on the equally free Design Spark Mechanical. When there's a new update to FreeCAD I take a look and nah!
Not "equally free", by far not. FreeCAD is free as in freedom, open-source software that nobody can ever take away from you. DSM is free as in a freeware software with online activation that lasts a year - and then is hopefully continued at distributor's descretion, and so far this has happened automatically. But one major reason DSM exists is in order to sell its parent software - SpaceClaim. The feature set is nice and high quality but is deliberately limited. If you want to take your objects to manufacturing (which isn't 3D printing), you cannot export a STEP file from DSM. You can lose access to DSM and to your source files that you created.
Unfortunately, FreeCAD is neither particularly elegant nor particularly robust.
Following your exercise with a few simpler shapes FreeCAD constantly falls over. V.19 and V.20. I had been using F360 and the earlier this year they got greedy and that was the end. FreeCAD however is no substitute for F360 because the workbenches are so poorly compatible. FC isn't F360 !
