Sketch selection and delete bugs

[scottmoyse]

I've created a video showing UX issues with sketch element selections, but then either a selection or a delete bug, where all selected elements aren't deleted.

Scott-

Thanks for the great video showing some issues with delete and selection.

The critical step is in the selection filters.

With the filter set to all objects, and a window selection is made as you are doing, certain very predictable things will happen. Faces will get deleted because you have selected them, for instance.

In your video you turned off Select Through. Select Through allows the selection of entities that are hidden by model geometry, on the back of your part for instance. It appears that any projected sketch edge that is at the root of a 90° vertical face cannot be window selected from the orthographic view that is normal to it - unless you have Select Through turned on. This certainly looks like a bug and we will investigate it.

In the case shown in your video, turn on Select Through, activate only the sketch selection filters, and make your window selection. It should work better.

The other issue you found is that window selected objects do not respond to the delete key, but do respond to the Delete command. This should also be investigated by our sketch experts. Thanks for showing us this!

Thanks,

Hi Scott,

Thanks for the video which clearly shows the problems you have experienced.

As Phil mentioned, when Select Through is turned off and sketch curves are overlapped with body edges, window-selection can only select the objects closest to eyes (i.e. depends on the z distance). So to delete the inner loop in your case, you can turn on Select Through (as suggested by Phil), or turn off the visibility of bodies from the browser.

There are couple of issues we could improve:

1. Body are deleted in sketch environment - We’re aware of the problem and plan to improve it. There should be no reason for the deletion of bodies or components within the sketch environment.
2. In your video, when Select Through is turned off, window-selection from the orthographic view can only select the 4 arcs (and therefore only the 4 arcs are deleted when pressing Delete key, which was easy to confuse users that Delete key doesn’t work). We will investigate why the arc behaves differently with the projected linear lines.

Thanks again for bringing this out.
