The black buckler here is an pyramid with an oval base and circular top where the top has been crushed in 4 feet.
Would there be a simple way to create such a surface in rhino?
If you are talking about the canvas / rubber ?? black area, my answer would be no. I would do that with T-Splines on Windows Rhino.
If I was to do it in straight Rhino on Mac I would do it one of two ways.
-
Make an open cylinder shape and point edit it.
-
Build sections separately with sweeps maybe and then blend section together.
Both would take some time.
for one I would extrude a circle to get a cylinder extrusion. Then ConvertExtrusion to turn it into a surface and then rebuild surface points.
Scaled with gumball …
Manual manipulation of points …

That kind of part (seal between the barrel cannon and gun carriage, or shift lever car, oppre joystick control etc.) I made several times. In addition to the method indicated by @rhinorudi (that sometimes replace it with the “cage” command I would advise to try to move the points, as well as with the gumball with the commands shown in the screenshot attached. Note that need 3 points on axis to maintain continuity curve G3

Thanks for the suggestions. I will work on it.
For now I’ve kept the shape changes subtle. I should have a different shape for each gun but I’ll probably live with that.
