Topic: Viewport Boundary

[Shoey]

Hi All,

When a polygon viewport has had its polyline boundary deleted and the result is a viewport without a boundary visible, is there a quick way to recreate the polyline viewport boundary?

Cheers

Turn on or thaw the layer that the viewport is on.

Thanks for your reply Robdraw.

I should have mentioned that the layer the viewport is on is on and thawed in both global and paper space viewport states.

If you create a polygon viewport in an empty drawing and erase the associated polyline you are left with a viewport with no boundary. Try it!

An existing drawing we have has this problem, however we can resolve the problem as we have a bak-up of the previous revision which shows the polyline boundary so we can copy and paste this in.

Just wanting to know if there is a quick way to recreate the boundary. Lisp perhaps?

Im using AutoCAD 2011.

I can't recreate the problem and it seems my previous answer doesn't even apply. My ploygonal viewports are single objects. Nothing is left behind when I erase one. Not like the older AutoCADs where you had two objects, a viewport and a polygon. Are you sure that the viewport is still there and your not seeing a ghost of the one you just ereased?

Here's  how i recreate the problem - using AutoCAD 2011.

Create new drawing.
Go to paper space layout.
Draw a polygon viewport.
Use QSELECT command - Filter for polyline in Object Type list and hit OK.
Erase selected polyline.

You should now be left with a viewport with no boundary visible.
You will be able to use and select this viewport in Qselect.

As mentioned, just querying if there is a way to recreate the boundary for the viewport.

If the drawing has not been closed before you want to get the boundary back, this works:

Code: [Select]

(setq elist (entget vport_ename))
(entdel (cdr (assoc 340 elist)))

However, once the drawing is saved, closed, opened, the VP still thinks it is clipped but the clipped boundary is no longer used...instead it is back to rectangular viewport.

given that the boundary is/was erased, and the viewport remains, why would you want, or need the boundary back?

[Shoey]

Thanks for all replies.

I would have liked the viewport boundary back because (in my own opinion) working inside a viewport without a boundary does'nt feel or look right. This minor issue does'nt stop me from continuing with my work though!
