Boolean edges
show user profile  jpedleham
Hey,

Is there a way to clean up Booleans?
I always end up with weird edges into the middle of geometry.

Thanks

Why would you use a boolean in the first place? If you use a spline there's no problem.

Basically i have construction specification drawings from a manufacturer, im taking them (pdf) into illustrator and exporting as a dwg so i can extrude the shapes but sometimes for some reason the shape in the middle (the parts i have to boolean) dont extrude as if they arent part of the same spline so im having to boolean out the parts i need bacause of that. Whats weird is it works absolutely fine in sketchup.

could it be that shapes are not welded properly?
Turn on vertex numbering in your spline and you wil probably see 2 vertexes on the same spot that need welding. Could be that sketchup autowelds on import.

When you export from illustrator use AI format, you may have to delete duplicate splines but they usually import and extrude fine.

..but yup, check they are all welded, uncheck end caps on extrude to see if it's extruding but not seeing the centre bit.

edit: export using illustrator 8 format.

thats entirely possible that they arent welded. Ill check back tomorrow.
Damn...i didnt know you could import .ai into max. Thats awesome!
Thanks guys!

I feel we might have a different idea of what clean looks like, to me clean is more or less evenly spaced quads.

Are you thinking of simply having no edges across the top face? and why would you mind if you do have those edges there?

For parts like this I would create more edges on the top face and remove the weird long ones booleans add, than you can usually chamfer the edges to give it that nice look.

Its for chamfering the edges yeah. I dont mind having the edges ontop, its just alot of the time the boolean edges will completely fuck my model and max will crash if i even go near the chamfer button :P

Ah yes! so just create edges that take a shorter path!, and once you have a few of these max should allow you to remove those giant useless ones and chamfer 'should' work, a bit of trail and error required though.
For each standard hole I try to have 4 edges going outward from it

Be thankful Max is forgiving with its chamfers! you may not think it is but oh man does it change in other applications.

There are alternatives to chamfering..like beveling the top/bottom, or the border faces, or using shell with a custom curve for instance, extracting splines and sweep then cap,..
Work around the problem if that's quicker.
