You can generate masks for ACES simulations using AutoCad as follows: Make sure you set the drawing background in AutoCad to white. Draw your mask, using "solid" regions in black, then export the drawing as a bitmap.

I4m using FreeHand (a vetorial editor) to generate the masks and to export in BMP format, but I4m facing some ems with this procedure (distortion of the dimensions). Someone know some way to use AutoCad or LASI to generate the masks or have used the CIF or GDS formats in ACES simulations?
