What happened to Boundaries ?

I never tried that in previous Bricscad Versions but I am not
able to get any Boundary over more than one 2D Object.
(Something like a Boolean Union, as the Tool Icon promises)

I can only get the "Fill Bucket" or Boolean Intersection Mode
of any 2D Geometries.
TAB or CTRL doesn't switch any Boundaries,
The Draw/Boundary Tool says 5 Selected, 0 created,
and if I trie harder - Bricscad v19 Win crashes.

I am I doing it wrong or is there something broken ?


  • Booleans are for regions. First convert polylines to regions and then use booleans.

    Thanks CADMebel,
    Although I recently learned that Regions are ACIS (Solids?),
    Boolean Operations only work for real Volume Solids.

    But I mentioned Booleans only to describe that "Boundary Selection Mode"
    or (2D?) Boundary Tool for me will only work for interior Boundaries
    inside Borders of any 2D Edges.
    What ever I try, I can't get them to select the whole outer Area of
    e.g. 2 Overlapping Rectangles.
    Basically what their Icon shows and promises - and what I think to have
    seen in Videos in the past.

    If you hover an edge, coming from the inside it will choose the next
    inner Border - if you hover over the edge coming from outside,
    it would choose the Boundary around ALL Objects.
    That is what I remeber.

    Thanks for the Lisp CADMebel.

    I may have dreamed or wishful thinking.
    Also tried in v18 on Mac.
    Looks like that "outer Boundary" Feature never existed.

    I was thinking about that Video, but inner Boundaries only ....

Origami is the Japanese word for paper folding. ORI means to fold and KAMI means paper and involves the creation of paper forms usually entirely by folding.
