    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
    1. Choose Adv Geometry from the GEOMETRY menu in Sketcher.

    2. Choose Blend Vertex from the ADV GEOMETRY menu.

    3. 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.

    Thanks

    insert/advanced and then what? --there is no Blend Vertex here
    Am I missing something?
    Thanks

    Sorry, again, hope you read remaining posts which correct the confusing one.

    Could you describe what you are trying to do or what your are expecting to
    happen?
    We might be able to help you better if we knew.

    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.

    Maybe you've given up by now, but the thing will work. I just did it on Wildfire, square to circle to triangle, with a vertex of the triangle as a 'blend vertex'. Here's how:

    1.. Have to understand how Pro/e 'thinks': it is connecting, from the 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
    2.. So, all of the start points should 'line up'
    3.. And, a geometric entity, like a circle without the number of natural vertexes, needs to be broken to have alignment points, usually the same number as the vertexes in the section before
    4.. The blend vertex occurs in the section with a geometric entity 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)
    5.. Don't toggle section again, just click OK to accept the sketch and OK to finish the feature. Give it the distances between sections and it should generate your blend.
    If you get twisting or the blend vertex is in the wrong place, you can 'Edit definition' to change start points or change which vertex is used as the blend vertex.

    Post a jpeg, if you do one. I'd sure like to see that.

    I can do an example but is it ok to post attachments in this group?

    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.

    Doesn't look like attachment are compatible between newsreaders, now
    I can see this in OE but not Gravity. I need to check this out.

    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.
