XCLIP PROBLEM

[Towny1]

My problem is this...I have an XREF in a drawing and want to delete/hide a small part of it. The object of my frustration is in the same layer as a significant part of the drawing, so I cannot turn it off. I tried XCLIP but the region outside the clipping zone gets hidden, not the small part I want to get shot of. Is there any way of reversing the clipping selection so that only the items inside the clipping polygon are hidden.

Any comments would be appreciated,

If I ever want to remove a section WITHIN the main body of the XREF when I'm clipping I do the following.

Draw two rectangles, the first one goes all around the xref in question but make sure it's clearly bigger. It doesn't matter if it's miles bigger. The second one is drawn exactly over the area you want to REMOVE from the middle of the xref. The next thing to do is draw two parallel lines that are very close together (say 1 unit apart) linking the inner rectangle with the outer, larger one. Now you need to trim these lines and join them up to create one continuous polyline.

If you were to follow the line from the outside rectangle it would flow into the middle via one of the lines close together, around the inner rectangle and back out, via the other parallel line, to rejoin the outer rectangle again. Now when you CLIP the xref select the inner part you want to remove and it will be trimmed out. It works because Autocad thinks that the line we've drawn represents an outside boundary. Since the 'joining' lines are so close together when you print it off you wont see any 'breaks' in the background xref.

You can create a variety of clip boundaries using this method, they don't have to be rectangles of course.

I've used this method on several occassion, good if you want to clear plan space in order to get a few details on your drawings.

I hope I've explained that well enough, if I get a chance I try and draw a diagram (of sorts) but you lose all the text formatting in this forum.

Anyway, I hope that helps.
