Attached file has a rectangular object with an internal island. Both are polylines. Most of the times, the polyline offset command does not see the internal polyline and writes the whole block full of parallel lines. I have tried to change the polyline direction, regenerate them etc, but if it properly generate the pocketing area is a hit or miss. What is required for both polylines to keep the inner line as boundary?
Thanks, Rob

Re: Pocketing
Hi Rob,
I recommend to use a single offset plus an exploded hatch to pocket that area. Depending on your needs it could look like this ....
BTW: Lunch in this drawing also the "Detect Zero Length Entities" tool to get rid of the "imperfection" ...
The Polyline Offset tool is not able to detect the inner polyline by design.

Re: Pocketing
To make sure the offset tool recognizes islands, you need to select all the contours and then use the offset tool:

Re: Pocketing
It's easy to miss as it's an unusual use of selections. But it's the only convenient way to "choose" multiple entities for an operation.
Re: Pocketing
Thanks,
I got the method from this forum topic:
https://www.qcad.org/rsforum/viewtopic. ... php?t=5411
In trying, I selected probably everything a few times, hence that is why it sometimes worked.
Will try again.
Thanks Andrew.
Edit: Just tried again, and now I see that there are two icons for Offset: Polyline Offset (alternative) in 'Misc Draw' which I used all times, and Polyline Offset in 'Polyline', which worked as desired. No idea what the difference is.
