Hi,
the crush is caused by IDrawLineTool Selected property.
since it's on your fix list the issue can be dropped for now.
but i don't like to know that the slope of line is not what one can expect

When an user selects the extention line it tries to switch to first (main) line since the latter should be used to handle dragging for both lines. Firstly, the second line i...

Is that Steema's way to treat customers? Blaming them with "souting" instead of mere answering a quistion? Have you ever read user's postings? I've asked a simple question what the purpose of IDrawLineTool.FromPoint (ToPoint) properties? to your information there is none (nada) examples on IDrawLine...

but you didn't answer on my question
what the difference between IDrawLineTool.FromPoint (ToPoint) and IDrawLine.StartPos (EndPos) properties?
Actually, I understand what is IDrawLine.StartPos (EndPos) for.
what the purpose of IDrawLineTool.FromPoint (ToPoint) properties?

Hello,

what the difference between the properties?
IDrawLine.StartPos (EndPos) set start\end points of corrsponding line.
but what the purpose of IDrawLineTool.FromPoint (ToPoint) properties?

nefis
