Impossible lofting, Extruding.???
on Aug 5, 2005 at 2:08:04 pm

How can I; Loft between two surfaces/ Extrude a surface so that it is proportionally smaller (or bigger) than the starting curve. ex: Bevel the letter A or R and most of the time it gives you a completely distorted mesh.

I think you can select the curve (ie a letter) and use the offset curve command to create a new curve thats smaller or larger than the original one.

as far as bevelling goes - I usually bevel edges and not the object to ensure decent results.

When you do that the problems start happening; The curves don't have the same vertices anymore and so they don't match up when you Loft or Birail them.

what end result are you trying to achieve? are you creating bevelled letters (its mentioned in your initial post-up) ? if so the bevelplus tool takes care of most bevelling and wotnot

sorry if I'm sounding like I'm making you suck eggs there - just not sure what end result you want?

Thanks. No Sweat.
I'm making a steel door where letter's have been printed/slammed into the surface.

I've had this problem before though; Lofting between curves that have been modified (IE: offset) seem to always get ditorted. I feel like an idiot for not being able to figure this one out.

could you not use a displacement map on the polygon face (assumption that its polys there!) to displace the surface? Afterward you could use displacement-to-polyons to turn the displace map into a polygon surface?
just thinkin on my feet here for you :)

failing that...

you could try using a boolean - again - poly solution but creating your 3d text and chopping it out of your flat steel surface might get good initial results. you can then select the face thats in the surface and use polygon extrude's offset command to get a slight bevel on the inside of the face?

Great workaround. You rock!

Doesn't solve the nurbs 'thing' but thanks a bunch. I'll do that.

its worth doing man - mental rays displacement is really good so you could create your indented text that way :)

Offset Curve Works properly. Like 99% of Maya; the right settings in each command/tool need to be declared. Mainly the 1 in question is "Max Subdivision Density", when this = 0, no additional knots/CV's are placed to maintain curvature, yet at times to reproduce proper curvature, extra CV's are req'd. I recommend setting this to 0.

Also turn on Loop cutting for convex curve intersection trimming.

Take that back...:(

Having a hard time with offset curve right now, I'll let you know when I figure it out again, it's been a while.
