I have created a region and made it transparent. It looks perfect on sheet however when I take a plot transparency is not taking effect (even enabling it in printing setting).
another trick to print with transparency without rasterizing is to assign a transparent display style to specific elements. Not sure which version of microstation you are using, that trick works for me in SS3.
Could you please explain more...?
You can change the display style of elements independent of your view. So you can select a display style with transparency override, and that will be honoured when when printed. Attached is the sampled pdf, the transparent element has a priority of of 10 and the other non filled shape has priority of -10
this will also hold for 3D elements
Thanks for your help...
