[SOLVED]PolyExtrude Like Bevel Profile In Blender?

[Atom]

Hi All,

I have a font object and I want to extrude it using the shape of a curve to create a custom extrusion look. I have dropped down a curve and connected it to the second input of the PolyExtrude node but no matter how I move the points of the curve around, no useful extrusion is ever produced using this technique.

 

Is there a way to emulate Blenders method for profile beveling in Houdini?

depending on what extrusion you're after, this method might not be what you need, or what you think it is.

Don't think of it as a "profile" of extrusion, it is a spine of extrusion, which is very different.

with the curve you can see in the picture, a profil would give you beveled font (like the 123 on the right), but the same curve used as a spine gives you the 123 on the left.

 

that's just to (try to) clarify the polyextrude node, now about how to recreate the profil beveling of blender or max, I would need to search too, so I'll let more advanced users help you.

have you seen this?

from 3:00 further it is pretty much showing exactly what are you asking about.

I did watch that video and now revisited it. PolyBevel is close but I can't seem to align it correctly. When I apply it to the font it only bevels the stroke of the font. I am trying to bevel the extrude edge based upon the profile curve.

I seen the problem, and it makes me think that may be, you should build the side first, then cap.
Like a sweep of your profile along the font (un-extruded font), to get the sides. Then cap the front and back.

But, to be honest, after a quick test, the sweep is making me loose my nerves. It works, but there's some clean up to do on the font first.

I'm now curious to see if there's a clean way to do this in H.

atom? found a solution? tried the sweep+cap ?

Hi Atom,

I would try extrude instead of polyextrude (see attached pic).

Thanks Nico, that looks right!

Am alone to think the Sidefx Polyextrude could be improved? Here, it was on a planar shape but  putting down a full complex networks to bevel pieces of a voronoid fractured relatively simple geo, gets me wonders.

I guess i missed something? And the custom curve profil input, i don't know but itùs realyl a fight for such a basic but essential operattion. Or am i unlucky with my with my model or so?
