I can only apply one mask to a surface?

[Anonymous]

Is there any way to apply more?

The situation, I just want to break the contours at the building pads. I
really don't want to have to use boundaries, and I know it could be done
this way.

It just seems that for this instance, multiple masks would be easier.

Hi Ron,

We have an automated routine in RDV that should do the job for you. You can
download RDV and use that portion for free actually!

The routine I believe is called building pads. We wrote it for
visualization purposes but it should do just fine for your purposes as well.
The idea is that you select a layer which should have closed polylines on
it - typically represnting the houses that you don't want to contour through
etc... It then goes and masks/ or boundaries - I can't recall exactly each
house automatically, producing the desired effect. Whats nice about it is
that you don't have to define each area one by one - just select a layer and
go.

I'd say that it would be definitely worth a look for you. Even if you don't
buy RDV - this routine is available for free in the application.

Ron,

Civil 3D supports multiple Outside Masks (show contours on the inside of the
mask), but only a single Inside Mask.

Are all your building pads the same shape? If so, why not make a block representing the pad and include in the block a wipeout that resides just below the linework of the pad.

When using this, either bring the pads to the front (select one, right click and "select similar", right click again, go to display order and pick bring to front) or send the surface to the back (using the same procedure). This eliminates the need for using multiple hide boundaries.
