Problem- clean up

[Claude Boudreau]

Iam carving flowers with v-cutter. I draw a simple 3d close spline for the tool path . Now my problem is to clean the inside of the petal, I cant seem to make a surface of a close 3d spline . witch way should I go? I have done it with offsets but it does not clean smooth enough.
Its the flower at top right on attachment.

Why would you go through all that work. If you run the BobART in V23 you can do this automatically?

I spent about 5 mins tracing over your drawing with the spline feature in BobCAD. Then I used the pull and tug feature to smooth our the same and get thing close.


This was your drawing:





In blue is the spline I created with BobCAD.



When you get the BobART software with BobCAD you also get the V carve tool path.

This will let you carve with a v tip cutter in 3D based on a 2D profile. It also has a cool clean up feature that lets you "rough" the shape out with an endmill first and then come back with the V tip for the walls. The picture below is the tool path. 2 colors because there are 2 tools being use.






This one I just used 1 tool , the V tip cutter

If you are trying to create a surface you would need to draw the wire frame for it, Which you have some of, and do a 3 or 4 edge surface or cross section or skin to create the shape you want.

Sorry I posted the wrong drawing . Forgot to say that I am still with version 21, So I have to draw my own toolpath by hand for v-cutter.Now if you look at the flower on the top right of the drawing (hope it is the right one this time)its this type of petal I want but i need to clean the middle of it . Now that I think of it , it might be a geometric impossibility to create a surface with a single 3d close spline?

I think you can get what you want here but you have to give the pedal some kind of "Spine" so the surface knows what to do in there. Same as a leaf.

Here's a small sample with the spine I mention. You can use this as a reference and re-evaluate how your drawing your leaves.
