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.
Re: Connect two extruded solids (cylinders)
Hello Matteo. Assuming the Front plane is in the center of the part, create a sketch on that plane, making use of the sketch's Use tool to capture the relevant surface edges of the shapes to connect the rib to. Draw a diagonal line between the captured lines to create a closed surface. Extrude that shape to the desired thickness, making sure 'symmetrical' is checked off in the extrude dialog. - Scotty
Re: Connect two extruded solids (cylinders)
Rib Tool works well.
Make sure the sketch for the rib is down a bit from the top or the edges will run past in this situation and throw an error.
Re: best way for loft sections between two changing size faces in different parts
ah, I see. Well how about this then. wrap the sketch to the first surface then transform that surface to a new surface with a scale factor and displacement via mate connector. then just create all the lofts

Frame Cut Lists K-Factor is 1?
I have been looking at cut list properties a little closer lately and noticed that the cut list tool assumes that the outside dimensions of any rolled segments are representative of the final straightened segments of frame length. Recently we had some rolled round tube come out of the shop oversized and the fabrication team had to rework the parts, and only after I've been digging into the featurescript implementation of cut lists did it occur to me that the dimensions given by the table might have been the cause for the out of spec parts. Wouldn't it be more appropriate to use the mid-line of the frame for rolled segments for a closer approximation of how frames deform when put through a rolling operation? Ideally the ability to specify a k factor for particular bends would be best but .5 is surely a better stab than 1.
