Mask Areas of Your Drawing with the Wipeout Objects Feature
While working on a project for our client Green Theory Distributors, we discovered the usefulness of the wipeout object.
Similar to putting a band-aid over an injury to hide it, the wipeout object allows the user to manipulate a polygonal area in order to mask underlying objects with the current background colour. The user can toggle it on when editing and turn it off when plotting. For our purpose, we required it to Mask an object during plotting.
When it comes to using the wipeout object, there are some things to remember:
1. wipeout masks the object behind the area created. You can add in details after creating the wipeout, but those will not be hidden by the existing constraint.
2. To include a new object to an existing WipeOut control, use the Draworder command to hide those objects behind your new object. You can always reverse this for an object you want to be in front of the masking, but be sure to only select the objects you want to be brought to the front.
3. To ensure that your wipeout control frame is NOT plotted, before creating the masking area, do the following:
Wipeout - Frame - Display but not plot. After you have done this, you can draw. If it disconnects, you can always rerun the command to initiate.
. Next, create a custom Layer but do not set to non-plot. Otherwise your masking region will not populate during plot (unless that is your desire). Defpoints, is also not a good setting for these. Make sure you can manage and control them as you desire.
