I am drawing a map and have circular viewports to provide details of road intersections. The entire map is also drawn in ms with a the border in ps. So the circular vp is a vp over a vp.

I used circular hatch w color 255,255,255 in model space over the area behind where the circ vport would be in ps so that the linework there would be blanked out. It looks great, but whenever I edit a block in the drawing it forgets the draworder thruout the whole drawing. It is necessary to manually move the white hatch to above the map objects. I can't use the quick "bring to front" command because it brings it all the way front apparently and whites out my white vport.

Is there a better way or a way to keep cad from resetting the draworder every time I edit a block?
the reason I am editing the blocks is it's a work in progress and I'm still deciding how big I want symbols etc...

Would wipeouts work better? I googled circular wipeouts then thought I'd just take the quick and dirty hatch route. Looks good at least.

Thanks for any advice you can give!

I've used polygonal viewports shaped like this:

You can also do something like the attached drawing.

I thought that was possible. How did you do it and what version did it start being an option?

You want me to tell you or give you some time to figure it out  8-) ... it's been around for many years.

I wouldn't have asked...

Plus, since this is the answer to the OP's question and this is a place for answers...

Where's the fun in that  :-P

Create regions and use subtract ... then create viewport from objects.

That looks great. It also looks like I'll need to have my "viewports" in place and locked in before I do that. Am I correct? This is a drawing that will be added to over time. I might need to move/resize the blow-up areas more than once.

Also have to hope the old school boss doesn't open the cad file  :police:

hm...I'm liking the viewport clip for this application. I can add to the clipline as needed.
