Rifle stock modelling - need help

kristjanpg06 — Sat, 01 Jul 2017 02:43:37 GMT

Hi guys

I have a problem... like most of us do when posting on forums like this one (except those who always have the solutions)

I'm trying to draw a rifle-stock and I thought I would manage to draw the stocks myself but it seems that it‘s a little more complicated than I thought it would be.

I've already made mesh file (from a handmade gun-stock prototype) with my CNC router by using a digitizing probe and WinCNC and I've put the mesh inside Fusion where I've drawn the buttstock and forend but I‘m having trouble getting it all to gather smooth and beautiful.

I only digitized the „grip“ and wanted to draw the other parts – hope you understand what I mean.

I need help and I'm willing to pay for the help!!

P.S. Sorry if my english is bad. I'm from Iceland so it's not my native language.

The grip looks like a "quality" mesh as expected with a precision digitizing tool.

That mesh if it's quad mesh ( a mesh consisting of rectangles rather than triangles) can be converted into a T-Spline, which can then be converted into a BRep (solid body).

It would probably help if you could post your design and maybe even the original mesh file in .obj format.

As a general rule, once you started a design as a T-Sline it makes sense to continue working with the model as a T-Spline, ut again, post your model and maybe an image of what you're after as the overall goal and we take it one step at a time.

Thank's for your comment.

I took the model back and forth from Fusion 360 to Meshmixer and converted to quads using Remake and I think I finally got it right. Now I can edit the grip very easily using Meshmixer and import it to Fusion. I think it's much easier to edit the mesh using Meshmixer rather than using the sculpt feature inside Fusion.

Well, yes, but the reason for that is that you would never model such a dense mesh in Fusion 360 to begin with 😉

the geometry of that object can be captured with 1/10 of the quads and then is not only fairly easy to modify but also yields a better quality surface.

If what you have, suits your purpose then that's OK.
