need somekind of tool that allows to cut meshes

riklopes

Hey guys, im currently in need of some kind of tool to add to this specific workflow where i need to cut a mesh in specific areas.

Say you have a sofa that is a single mesh, but i want to cut it on the side pillows and on the seats so then i can select them independently.

I know how to do this in max, i can draw a line where i want the cut and it creates the needed geo. The problem is i need it to cut straight away as i paint the lines.

Does anyone know anything that could help me with this issue?


Thanks in advance

Can you elaborate on this part a bit? It's unclear to me what you need. Cut tool? Maybe with Snaps? What kind of painting are you referring to?

A screenshot would probably help.

sorry, for example, u have a sphere, and u draw a spline to cut it in half, and as u do it, it separates the mesh into two as you go.

is this clear enough?

riklopes

that would work if i wanted to slice a mesh in a straight line, but what im trying to do is to cut a mesh on random places

and also, when you slice using the slice tool, u dont get the mesh split into two, the only thing you get is new geo.

Use the Split checkbox with the Cut tool.

yeah thats almost what i want, the only thing left here is if i could paint drag instead of clicking where i want the cut.

For example there is a tool in the graphite tools that works similarly, "P Connect" u can paint the vertex wherever u want on the model.. if there was a way to combine this with the split feature.. that would be awesome

It sounds like he wants to use a bezier curve or something as the shape of a slice. I imagine the easiest way to do something like that would be to make a line of verts extrude in the direction you want and then use some sort of boolean operation. Not sure how that works in 3ds max though since I mainly just use Blender.

What I dont understand is if he specifically wants it to be like drawing the curve on the geometry itself or if the slice would be projected from viewport or what. It seems like an oddly specific request when I imagine you could just use a knife tool to cut up the mesh where you want before dividing it into different meshes by a selection.

Does 3ds max have a knife tool that works like that? I remember using the knife tool in Maya and Blender to get that result.

in maya you can project a curve onto the surface of a mesh and then use the 'split mesh from projected curve' under the edit mesh menu

If you use Zbrush you can use the Trim brushes
