Re: How do I design Gear ring with external and internal teeth

hi dave What are you trying to do? form 1 or form 2? Hi meme2704, the picture quality doesn't give me precise answer, but the inner teeth in you picture are not real involute teeth? Are they result of substraction of involute gear from a cylinder (thus invalid)? In case they are valid inner teeth, ...

Re: Assembly3 preview

...you can do that by wrapping the array in a sub-assembly. For draft array, you need to set its `ExpandArray` property to true to make its element freely movable, so that they can be constrained individually. I'll try that. I used Draft WB Array command , since other array methods (Part Design WB,...

Re: Assembly3 preview

I've been testing (and still am) the 0.8.1 since the release date and it seems to me like a giant leap forward! Great job! And there's 0.8.2 already... :-) I found some minor , low priority issues: 1) Array cannot be constrained (or I did not find a correct way to do it) ASM3_ArrayErr.PNG Traceback ...

Well, it depends on definition of "multiple bodies". I did FEM analysis on welded assemblies in FC 17. I used some solid boolean commands from Part WB to get one object to mesh. If used correctly, it provides valid results.

Re: Assembly3 preview

Regarding to #2, I'm convinced that it can not be done unless some scripting is involved, so it should be left out of ASM3 context. Thanks for the answers, I'm moving forward. You could/should use Spreadsheet workbench to drive the dimensions in a logical way. No scripting required, if I understand...

Re: Assembly3 preview

This is cause by FC's labeling policy. The default is no duplicate label in the same document. It will auto re-label by appending digits. So it is better not to end your object label with digit, or else you'll get confusing re-label. You can change that policy using Preference->General->Document->A...

Re: Assembly3 preview

Hi Realthunder and the team, I cannot wait to test 0.8! Specifically the multiplication of the constraints looks impressive. In the meanwhile, I have some reports regarding previous version. Shred it if it's already fixed :-). 1) Dropping part into assembly Parts container gets (sometimes) wrong lab...

Re: Assembly3 preview

I set on to test the constraints of grid and cubes (bases) as per your suggestion (@realthunder) with the 25 links. However, I found out, that in the scenario I created, it is not possible to select same objects (lines, faces,...) on different links at the same time . I don't know what's different f...

Re: Assembly3 preview

Using sketch lines is the easiest way, or you can try SketchExport , which allows you to export sketch points and construction lines. You probably should also create a circle for easy locking of the sketch. I'll try that, might be a good way to enhance such a work flow. Plane alignment can accept m...
