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:

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?

Adios,
