Hi, The following is an extract on adding a blend vertex but I cannot find the path to ADV GEOMETRY. Does anyone know where this is hidden in 2001?
To Add a Blend Vertex
Choose Adv Geometry from the GEOMETRY menu in Sketcher.
Choose Blend Vertex from the ADV GEOMETRY menu.
Select the vertex of an existing geometry entity. A circle will be placed there. More than one blend vertex can be created at the same point. Each additional vertex will create a concentric circle of increasing diameter.
Essentially I was trying to blend through a number of fairly equal sections with the same number of sides[ almost like the example in 'help'] and delete one vertex in the end section. When I saw that it was almost identical I was pushed to make it work but could not crack it. Whatever I did to the section with the picks would not be accepted and dropped out. I drew the first section.toggle, second section,toggle, third section with one side less and now anything that one done with the blend vertex pick failed. I must have missed the one correct action.
Post a jpeg, if you do one. I'd sure like to see that.

Wildfire, square to circle to triangle, with a vertex of the triangle as a 'blend vertex'. Here's how:
start points of all the sections, all of the vertexes, one by one, then using this as the template for blending from one to the other. You could think of the curves that it uses to connect the vertexes as trajectories
natural vertexes, needs to be broken to have alignment points, usually the same number as the vertexes in the section before
having a fewer number vertexes, in my case, the triangle. When you have drawn the section, pick one of the vertexes so that it highlights. Go to 'Sketch>Feature tool', the 'Blend vertex' item should not be greyed out, pick it. It will use this point to draw the vertex in numbered order from the previous section and also the 'left over' point (4 vertices down to 3)
OK to finish the feature. Give it the distances between sections and it should generate your blend.
'Edit definition' to change start points or change which vertex is used as the blend vertex.
I think many groups frown on attachments when they are are unexpected as they expect to download the mail for offline viewing. I also think that more should be made of visuals especially in a cad group. Anyway, this example isn't exactly what I was doing but simplified to show the logic. It's a pity it only works on the last section.
The attachment didn't make it. My news reader (Outlook Express) also doesn't show a flag for an attachment. I've never seen a help or hint on how to attach a file. I mean, I know, anywhere else in the universe, but not on Uselessnet. Something I should look into. I'll post an item on it. Anyway, this group is not monitored. Only two FAQs on record with Usenet, both from
1996 ~ highly outdated lists of graphics cards, useless shit on Uselessnet.

Can't post a picture to a text only newsgroup. Most news servers kill that type of attachment to conserve space and reduce bandwith. Try posting it to one of the binary graphics groups then tell us where it is or stick it on a web site.
Yes, they are on alt.binaries.pictures.misc and once you glue them back together again, look fine.
I see now what it's doing. You're telling it how to divide up an uneven number down to an even number of vertices. If you had just told it which two vertices to blend to, it wouldn't have known which to give three vertices to and which to give two to. The concentric circles show the number being blended at that vertex
Very cool, but like a lot of this stuff, you may learn it and never have occasion to use it or if you do, have to go back and relearn it. But it's nice to know it can do it. Thanks.
