Mask a view port

Is it possible to mask a view port below an existing viewport so it doesnt show through. Im using autocad 2006 lt.

Why not just use a polygonal viewport, and draw it to the shape you want?

I'm positive there's a button for this, on the viewports toolbar, but just in case:

(command "._-vports" "_polygonal" pause)

[edit]

I don't have AutoCAD LT, this may not be an option...?

2006lt doesnt have that option.

Back in the day... when I was relegated to using AutoCAD LT... I created a hatch with a color that plotted as transparent (255 for my CTB). Then I would stack mview on top of hatch on top of mview to get the desired effect.

viewports inside viewports - 3 methods

1) First draw a rectangle that will be the size wanted for the big

viewport. Use the Region command and make that a region, now use the

Mview command, Object option and pick the region. Adjust the view in

that viewport accordingly.

Now draw circles or polygons, etc. that will represent the smaller

viewport(s). Place those where you will want them. Use the Region

command again. Use the subtract command and pick the large region

then the smaller one(s). Now draw the circles again in the blank

space, use the Mview command, Object option. Adjust those viewports

accordingly. Because these are regions now you won't be able to edit

them like a normal viewport, IE: grip stretch, etc.

2) In MS use wipeout to hide the area you want another VP to reside. Now in PS use MVIEW and grab the opposite corners of the wipeout.

3) In PS you can draw a continuous pline with a large rectangle and then move into the center and draw a smaller rectangle, all in the same pline command. You will have two plines one of top of the other going to the smaller rectangle but that is ok because it won't show. Now use the MVIEW command and use Object option. Now use MVIEW again to define the smaller viewport grabbing the opposite corners of the small rectangle.
