Have you ever wanted to hide both AutoCAD and AutoCAD Architecture content such as lines, hatches, text, walls, doors and windows? Well, a Wipeout will only work on AutoCAD content and an Mask Block will only work on ACA content. The solution? Something I haven't had to use in a while but was brought off the shelf for a customer recently - the AEC Polygon tool.
To find this tool, do the following (see images):
* Click your Content Browser
* Click the Stock Tool Catalog
* Click Helper tools
* Click AEC Polygon tool eye dropper
Then, fill the eye dropper up, drag to model space and pick points to outline the area you want to hide (similar to picking points for a wipeout). You can edit the AEC Polygon style to set specific things you want it to do such as using a Background Mask, telling the edges to be set to a no plot layer, etc.
Its a fairly simple Style to control in ACA since there are few options for it, but should greatly simplify your creation of areas to mask.
