--------- Hi.
quick question: how can i draw dotted lines in my tool plugin?
code from this thread doesnt work for me : link
it suggested using negative values for transparency.
greetings, Daniel

Dan had to create his own 'dotted line' drawing routine (probably using one of the line routines like Line2D, LineCS, LineStrip...). There is no built-in support to do it. Maybe he'll show up here and provide code.

It appears that void SetTransparency(LONG trans) with a positive parameter draws a dotted line and negative values draw true transparencies.
My test code:

yes indeed, thanks for that. must have done sth wrong with the code from the original thread..
I think the fake transparent look is just what i wanted!

Howdy,
Well, looks like this is another thing to add to the list for things to change in an updated SDK docs. I wish I would've tried 255 for the transparency back then. :o(
Adios, Cactus Dan

Hmmmmm, I've discovered something odd about drawing in true transparency: Transparency
It seems that virtual geometry doesn't draw behind a transparent polygon when "true" transparency is used the the virtual geometry is selected. Is this a bug?
