Hi,
there is a command-persistence bug in the view mode icon bar when using “view only intersecting supports”
As it used to be so that, when clicking the ( only intersecting supports) icon and then on “add single support”, the view mode remained on the selected.
As it is now, when you select the viewing mode and then on “add single support”, the viewing mode reverts back to the default viewing mode.
For placing supports, I do prefer the “only intersecting supports” mode , as it allows more accurate support placing, cause the feet do no obscure the positioning place.
As you can not click on the viewmode icon after starting the “add single support”, I found a work around, by using the keyboard shortcuts CTRL-SHIFT-I , after using the add single support command.
