sub-d newbie problem

[jupussi]

Hello

I'm having problems with sub-d:s in modeller. I seem to be creating polygons more than 4 vertices.

How do I get rid of this. Is there some tools that are not suited to be used with sub-d:s becouse they create polygons more that 4 vertices?

One thing that I have observed is that I have to knife the whole object, instead of just few polygons.

What do I do to those polygons that have too many vertices? Tripling is one option I guess?

The easiest way, while still staying in control, is to use the Split Polygon tool.

Yes, there are tools that create polygons with more than four points. Does that make them unsuitable for use with sub-d's? No. You just have to be aware of them, and you need to plan around the polygons.

This is true. However, if you select the polygons prior to using the Knife Tool it will only affect those.

Yes, tripling is a possible solution. As I stated earlier, using the Split Polygon tool is an option and gives you the most control. The Knife Tool, as you know, is also a solution. The Knife Tool is good because you are able to work on larger areas faster than with the Split Poly tool.

There are also a number of plugins that will enable you to get rid of the problem. There are edge tool plugins, etc. There may even be some tools that will automate the process, however, most of the time you sacrifice control for ease of use.

I would have to say that tripling polygons is not the best solution for SDS. Try to use 4 point polygons whenever possible. The best way to get rid of 5+ polygons is to use the statistics panel by hitting W while in polygon mode. Use it to select the offending polygons and delete them. Rebuild the areas with 3 or 4 point polygons

As far as tools not good for SDS. Any of the cutting tools like booleans or stencils will force you to manually fix areas on SDS surfaces since these could create polygons with any number of points as they intersect exisiting polygons.

You could triple polygons to fix polys with more then 4 points but it's sloppy to rely on tripling. The best thing to do is to plan out your mesh beforehand so you don't run into it. But if you do, use the k button to kill said selected polygon and then manually go around the edges and make new 3 or 4 point polys by selecting the points and hitting p for polygon.

LWs, native Split Polygons is tedious as you have to select both points and what polygon to split. Get SuperSplit or use EdgeTools Add Edge.

Other than that hrgiger is hinting something important: Don't limit your arsenal of tools just because they might create non subdividable ngons. If you feel a boolean would be the quickest and smartest solution to a problem, work with polygons for a while and just clean it up. Often when I build I use SubDs and still do booleans. It is important though that you know how you want your wireframe to look in the end so you know how to clean up the boolean.
