XClip

Select entities

Chooses the xrefs to be clipped:

• Choose one or more xrefs
• Enter all to choose all xrefs in the current drawing
• Press Enter to continue

ON

Turns on clipping boundaries that were turned off by the OFF option.

OFF

Turns off clipping so that all of the xref is again visible. The clipping is saved, and is turned on again with the ON option.

Clipdepth

Sets 3D clipping to the front and rear, to hide parts of 3D models that might obscure the front and confuse the back; prompts you:

1. Specify front clip point or [Distance/Remove] - (enter an option.)

2. Specify back clip point or [Distance/Remove] - (enter an option.)

This option does not operate until you create at least one clipping boundary. It is no useful for 2D xrefs. 

• Specify front or back clip point - specifies the position of the front or back clipping plane: pick a point, or enter coordinates. The cutting plane is parallel to the current viewpoint.
  
• Distance - specifies the distance of the clipping point; prompts you:
     Specify distance from boundary - (enter the distance from the clipping boundary to the front or rear planes.)
  
• Remove - (remove the front or rear clipping point.)

Invert

Inverts the clipping mode so that the interior of the clipping boundary is hidden from view (the the outer area is visible); repeat this option to invert again, making the inner portion visible.

It is much easier to toggle the Invert status through the Properties panel.

Delete

Erases all clipping boundaries; does not prompt or warn you.

generate Polyline

Draws a polyline over a selected clipping boundary: this allows you to edit the clipping boundary, but in an indirect fashion. Follow these steps:

1. Generate the polyline with this option, and then exit the XClip command.

2. Use the PEdit command to edit the polyline.

3. Restart the XClip command, and then use the New | Select polyline option to turn the polyline back into a clipping boundary.

New boundary

Draws a new clipping boundary:

• If a boundary exists, then you are prompted:

Delete old boundary(s)? [Yes/No] - (type Y or N.) Caution! This option replaces all existing clipping boundaries with the new one. The command continues only when all previous boundaries are deleted: typing No at this prompt cancels the XClip command.

• If no boundary exists, then you are prompted instead:

[Select polyline/Polygonal/Rectangular] - (type S, P, or R)

• Select polyline - choose any open or closed entity made from polylines, such as splined polylines, rectangles, donuts, and polygons. While the polyline does not need to be closed, it cannot cross over itself.
  
• Polygonal - creates non-rectangular clipping boundaries, with a minimum of three sizes; prompts you:

  1. Specify first point - (pick a point in the drawing, or specify x,y coordinates.)

  2. Specify next point or [Undo] - (pick another point in the drawing, or specify x,y coordinates.)

  3. Specify next point or [Undo] - (pick more points, or press Enter to complete the polygon)
     

• Rectangular - creates rectangular clipping boundaries; prompts you:

  1. Specify first corner - (pick a point in the drawing, or specify x,y coordinates.)

  2. Specify opposite corner - (pick another point in the drawing, or specify x,y coordinates.)
