- In this video we are going to take a look at the same glasses we designed with Solids, but use Forms. I had a request to shows forms and surfaces so here we go.
One important thing when starting a form is which body type should we create? A lot of the time a face or plane will work, but in this video we will highlight some different body types to show how easy or hard they are to work with.
If you want to try on your own you can download the dataset with canvas images here. a360.co/3CbJve0
And if you want to continue with the shape at the end of the video you can download it here.

great demonstration of how to use different strategies. Again high value content. Thank you
My pleasure!
making glasses for a cosplay and had no idea of how to do anything in fusion 360 but after watching this I now have a nice start to them
Great to hear! Also have another video on the topic using solids that might give you a few tips. czcams.com/video/pQF2QmF3cK0/video.html
THANK YOU FOR THIS NICE TUTORIAL!!
You are welcome!
I would be interesting to see how the grooves for the lenses would be done. Thanks for the video.
ill see if i can get back to that. The basic idea would be to use an edge on the inside to create a plane along path. this plane would be normal to that edge/curve. Then draw the section you want on that plane to do a sweep cut. In some cases you might want to use Sweep with Guide Surface and select the glasses to help drive the normal direction.
That was really helpful and seemed like the best way to model the face because it is a 3d curve. From a manufacturing process I understand that acetate is flat and heated into a curve. I guess you would model it flat and then the face curve is done in the factory? This ist relevant for 3d printing say a prototype.
some CAD programs will have a bend tool that lets you bend a 3d solid. In that case modeling it flat would be easier for sure. But yes if you want to 3d print or injection mold them it would have to be modeled in its final shape.
@@LearnEverythingAboutDesign manybthanks. Yes I’ve been looking how they make them. But I’d need the full product form in 3d first to test like you say. The guess the 2d CAD drawings produced by fusion they would take that into account? I’m actually an architect and am familiar with a number of cad programs. What do you think is the best software for building glasses as there forms can be tricky. Fusion 360 seems very capable and the price outstanding. Thanks again 🙏🏼
@@xpost92 I think i did these glasses as solids as well which was a bit more difficult. One problem you are going to face is flattening that is curved in CAD. There are a few options but here are some of my opinions/workflows to consier.
1. Model them flat, 3d print them, heat them up and let them resolidify in their new shape. PLA will do this just fine over some steam/boiling water or just heat.
2. Model them in 3d and use a program to get a flat version of it. There are add ins like "Exact Flat" that are costly but will allow you to flatten a surface. That doesn't really help with the details around the hose or pivots. Inventor also has a flatten surface that I do use. Generally this is meant to do things like make decals for curved parts or to come up with fabric layouts for composites.
3. use a cad program that can bend/flatten a 3d solid. The only one I have used in the past 10 years that did this "OK" was solidworks.
IF you model them with fusion Forms, you can flatten the form. depending on the curvature this might be an ok solution, but if you end goal is a flat part that gets formed, i would likely start with it flat. would be easier to 3d print and then you can form it(assuming you are printing with an FDM/FFF machine). This makes an interesting topic....
@@LearnEverythingAboutDesign thanks for this really appreciate it. It may require two models: a prototype model for design/rendering and a production model. The production model would prob be simple with the intent to produce 2 d drawings. What I have seen on such things as the temples or arms is they are drawn flat and then bent in the factory. This would imply they are “projected” views or flat. I’ve tried inventor, great program but expensive and prob has allot more than I need for simple small scale objects. At the moment I’m really exploring design but down the line I’ll speak to the manufacturer the best way….cheers
Loved the tutorial, was extremely insightful and useful! Was wondering if you have a guide on making the lens that fit the frames, or if you could tell me how I could do that? Thanks a lot, keep up the amazing work!
For this type of shape I would use the Patch surface tool but have an internal guide rail for the curvature. You can have ones going in 2 directions. That would be the best way to hit the frame where you want. The other way to do that would be to draw the lens shape first. I did a module series for Autodesk and the Rendering one has a pair of glasses you can take a look at. www.autodesk.com/learn/ondemand/module/fusion-rendering
@@LearnEverythingAboutDesign Thanks for the swift reply! I will be sure to check it out. Also, how would you recommend going about making the glasses arms and attaching them to the lens frame?
@@PhilW771 The arms twist a bit so I would make a few sketches and create a loft that twists. Over build it and then cut it away with a shape from the side. Well use Intersect when extruding and keep only the piece of the side profile of the arm. In the dataset in that rendering module you can see Loft4 is more straight up and down and Loft5 adds the twist part. Those bits are joined together and Extrude12 cuts away the pieces not needed by intersecting with that body.
