Support Question of The Day

Q. I have a quick question about masking blocks. Can you mask them? I made a utility sheet legend in block form and I paste it on top of paper space and would like to mask out behind it. ??

A. Yup! You can add a "mask" to a block's definition. The command to use is WIPEOUT (this is a key-in). After starting the command you can choose an existing closed polyline that will fill in with the mask. There are a few quirks to this command however: Quirk 1)The wipeout's draw order is key to getting it to behave the way you want. Make sure it is behind the block but ahead of the objects you wish to mask. Quirk 2) Wipeouts work in paperspace too. When getting ready to print, make sure the wipeout has not obscured text you want to see in the layout.
