View Full Version : Hard edges with sub-d, completly wrong approach?

01 January 2011, 03:26 AM
Hi all,
Modeling is one of those things that I really need to beef up on. Since so many people use polys these days instead of NURBS, I'm trying to focus on them. Modeling a metal plate for my telecaster project at first seemed like a really easy task. But the holes in the mesh have created some problems. I have started by creating a flat plane in the shape of the plate, then used the chamfer vertex tool to create polyz which I deleted to represent the round holes.

I used a couple edge loops to create square hole in the middle, or what I hoped to be square. You may not beable to tell from the attached pics, but there is a edge loop very, very close to the hole.

This plane needs to be extracted in Y to give it depth, so all of the holes are going to become soft, curved holes as apposed to a sharp edge like a drill press would create.
I was hoping to used sub-Ds so that I could increase the detail to get a camera close to the model. Am I going about this completly wrong? Should this be a non-smoothed poly object with lots of polys to maintain smoothness near camera?

I have attached 2 screen caps that I hope will demonstrate my current progress. Oh and the application is Maya, and I has hoping to avoid the Maya specific "Make Hole" tool, so that these learned skills can transition from package to package.

Many, Many thanks!

Here's an exemple ( of how i would do it.

I just started with circles and moved the edges to form the outher part of the rectangle, then i added the rounded ends of the plate, everything is still a flat plane at this point.

Once all the details were done, i added a shell modifier (it's essentially a 2 sided extrude) finally added support edges to keep the edges sharp where needed.

Thanks for the reply, read about but never used shell modifiers, but great idea to use them here!

I see that you used a good number or triangles in your model. In my model I was trying to keep quads, I should have mentioned that in my first post. I know that triangles will not fall victim to bumps in a mesh when they lie on the same plane. Is there a way to that? Still trying to tell myself that I should be able to make perfect meshes out of most models.

Thanks Again!

Triangles are acceptable when they are on a flat surface, or anywhere else, just as long as they don't create undesired artifacts (and unfortunately they do a lot). Keeping quads will lead to a much denser mesh on some occasions so cleaning up as you go along is a good idea imo.

I highly recommend watching Grant Warwick's hard surface modeling tutorial:

Good luck with the project.

Great Video, appreciate the help!
