Editing Regions

Anonymous — Wed, 31 Aug 2016 22:50:51 GMT

Hi,

I need to edit a regions without having to explode it back to lines,

Exploding it back to a closed polyline would be okay or even better being able to edit the region itself.

Hi,

welcome @Anonymous.autodesk.com!

>> I need to edit a regions without having to explode it back to lines,

Sorry, not possible.

>> Exploding it back to a closed polyline would be okay

(In most cases) You can use command _BPOLY to generate a closed polyline from the region (or more polylines if the region has islands).

AutoCAD's direct Region editing via Selection-Filter-Edge has continually gotten more competent over the releases. Moving edges, both internal and external, has been possible for a while. 2017 now looks to be able to Scale and Rotate features as well.

Look into that drawing, on the left side the original objects, from that I created a region using _BPOLY and moved it to the right.

Now try to modify any segment of that region 😉

On my system (AutoCAD 2017 SP1) when you select an edge the complete figure/region moves to the right.

Combined with the limited handling (no grips, not all commands like stretch) I would say for me that's not editing like CAD should work. But mentioning that edges can be selected and modified was very good (as I forgot that option to write in my post).

AutoCAD's ability to manipulate spline geometry has gotten better over the years as well. But, if there's anything that will throw a curve to an AutoCAD operation, it will probably be spline based.

You can subtract and union regions, that is about it for editing.

Thank you,

That has solved my problem, the trick was 3d modelling workspace.
