Hide objects that cross a polyline

[JonathanEngr]

Hi, everyone.  I'm not sure if this is the correct place to post, but I'm using AutoCAD Civil 3D.  I'm not "rendering" 3D objects, so hopefully I'm in the right place.

 

I have a block that I created that is a camper spot on a project I'm designing.  It's basically a gravel pad for the camper along with a projection to the side for a grill and picnic table.  I would like to use this one sketch for all of the sites, but since the road has radii and curves, parts of the block will cross into the road, etc.  Is there a way to mask the block so it is "clean" along the road's edge?  I'm attaching a snip showing where the block (grey hatched object) cross over the radius of the road.  I would like the polyline that is the edge of the road to mask the portion of the block that goes outside of it.  Thanks for any help/advice you can give me!

As its a block its a bit harder to trim and maybe doubtful at all, 2 ways explode and trim then "group" so it behaves like a block. other way is to use a wipeout but that is a bit complicated to make as you have an arc and wipeouts only support straights, maybe  a 3rd is  hatch outside up to the arc set the layer to a no plot layer, use draw order to bring forward, in my limited testing seemed to work.

Just use a Solid Hatch with color 255,255,255 for the road with a black boundary which will always plot white and cover the block and set draw order of the road to above or bring to front and/or set the block to under or send to back. Also, if you want a different color any true color solid hatch will work.

Thanks SLW210 was trying to remember the color setting need RGB as you have suggested.

Johnathanengr I did something for road chevrons and could do a copy your pattern no infill, trim as required, then hatch all the shapes in one go. For the hatching you would make a list of a point inside each  entity as you copy then use that with hatch. This would allow a more random shape on the edges using trim to match outer edge, use say EXTRIM a express tool.
