Full Version: Blending Shapes

Show messages: All  1-6  7-11

I'm embarrassed to say it, but this I the first time I've figured out how to use the Blend tool, it works great for this application. I set the snapping to surface and drew a line along the profile to form that edge. It doesn't follow the surface perfectly but close enough that the trim command cuts a nice clean edge. Then I used the blend tool and that got me most of the way. I turned on the surface points and drew a swooping line along the flowing ridge of points, skipping the ones out of alignment. After that simply snapping the surface points along the smoothed curve cleaned everything up in that compounded area.

Thanks for the help, this is excellent!

I'm starting go get a better handle on the blend command. I can see now what your were talking about on the surface and boundaries forming the edge.

Curve network sure does a nice job. If you take create accurate and smooth curves from the beginning it translates into some very nice surfaces. I need to dig in the forum and YouTube to better understand what you can and can't do with it.

Thanks again.

"For the second it basically doesn't work that way because trim boundaries don't control the surface shape directly, it's more like they live on top of the surface and mark which areas of it are active and which are holes."

If the shape data is retained when a portion is trimmed out of a surface (creating this inactive area you mentioned) Is there some kind of heal command that would remove this inactive area? Returning the surface to its full shape? I hope that makes sense.

Hi Craig,

There is indeed, it's called an "untrim".

It's done by selecting all the edges that make up a trim boundary and doing a Delete. The trim boundary must belong to a single surface, if there are multiple surfaces that are joined together use Edit > Separate on them first to break them into individual separate surfaces.

Got it. Hidden right there in the delete key. That is very cool, works great. I like the ability drag a window once in sub-object mode, here I've been selecting one at a time. Thanks!
