Boundary blend solid?

If your Boundary Blend surface / quilt intersects solid faces in such a way that intersect / trim / join operations would result in a volume definition it can be Solidify'd. Just select the newly created surface / quilt and see if the Solidify toolbutton becomes active.

Yes it does become active, but when I complete the feature the suface disapears?, I checked the info button which tells me it is a cut feature.

I cant see where to change that to a protrusion.

I'll give a little infomation about the part I'm trying to do. I have two solid rectangles one smaller than the other. The smaller one is offset above the bigger one. I clicked a edge off the bigger one & an edge off the smaller one. Then I clicked the boudary blend button which produced the surface.

Thanks

Clicked "an" edge

---- or --- chained enough edges to bound a "region" for each section, which is what I think you want to do?

If that's not it we can try to talk thru it or you can post models on forums like mcadcentral.com.

Ok, I see what you've got. The single, open surface will not intersect / trim / join to create a volume definition so the only option available is a Cut (and it errors since nothing gets cut).

So, what you want to do (a mini lesson in "chaining") is:

_ Select an edge. _ Hold the cursor over the edge until it pre-highlights again. _ Press / hold Shift. Notice the screen tip says; One-by-one. _ RMB to toggle thru chaining possibilities until it says; Surface loop, and the correct solid face is highlighted. _ Click to select the loop. _ Release Shift and press Ctrl. (You've completed the first section, Ctrl starts a new chain for the next section.) _ Select an edge of the second block and repeat the process.

You'll probably need to adjust the Start Point for one of the sections. Grab and drag or ... _ Click the Curves flyout tab on the Dash Panel. _ Click Details under First Direction. _ Options tab, Start Point.

The default Control Points won't be to your liking (why on such a simple shape is beyond me). _ Dash Panel, Control Points tab, Fit: Piece to Piece (is the easiest way and suitable for this application).

That should get you what you want (unless you want to constrain the boundaries tangent to the sides). Once done, the feature will still be in the Selection Set and the Solidify toolbutton active. Hide the BBlend quilt when done.

Thanks Jeff

I'll have a go and get back to you.
