Re: How do I solve this inverse kinematics issue
I'm guessing there the links already have mates that constrain them on the Z direction and there is mis-match somewhere (could even just be a rounding error in the math).
Change that revolute mate to a cylindrical mate to avoid this.
Re: Exporting assemblies as multiple .stl and retaining assembly origin
@eben_demong If you need a common origin and are exporting STLs as a final step, consider making a part studio in context, using transform with the copy-in-place option for all of the parts, then exporting STLs of the copied parts in the in-context studio. That way, all of the parts should have a common origin at the part studio origin. However, this may not work if your slicer is trying to be smart and comes up with its own origins or does something else (I have not tried this method yet--just something I came up with on the fly)

Re: Loft to get a cylinder with hole (a hose)
Loft help says "Nested loops in profiles are currently not supported".
However, you can do this with two loft commands. See the gif attached.
Re: New Feature: Poly-Mate Connectors
That's not even the other one I was using before, that's a step up from what I was originally working with but the polyhedron script I used in the demo of this feature takes the cake for me for sheer absurd volume of options. It was apparently based off the mathematic structures on this website.
I haven't exhaustively checked that they're all in the script but it certainly looks like the author took someone's joke of "Oh, you're a fan of shapes? Name every shape" as a personal attack and delivered.
Tutorial double feature: Mate connectors!
Hey everyone, I've been wanting to make some videos deep-diving on mate connectors and I finally did it! The first is all about mates in assemblies (share it with anyone confused about The Onshape Way) and the second is about doing everything except connecting mates with them. Enjoy!

Re: How Do I Make A 3D Wolf
Probably easier to get one out of a forest.
What do you plan to do with the wolf? 3D printing, rendering, animation? Does it need to be organic-looking? If it does, Onshape is not the tool for organic modeling.

Re: helping with the creation and smoothing of wings
If you look at the curvature of the original curve you created in the Profile generator feature you'l see it is not optimal for smooth surface creation. Since this curve is the basis for all subsequent features, you will face difficulties.
I have found that using two splines: one for the top surface, one for the lower surface is a good idea. The Profile generator offers this as an option, however the curvature of the resulting splines is still not create (since it is still using a fit spline on "noisy" data under the covers of that custom feature )
Last year I helped Holbrook Aerospace create a new Custom feature that tries to address this - HAVF Profile
Alternatively you can use an Edit curve feature after the current Profile generator and do some reapproximation of the sketch, before it is used in the extrude and other features.
