It was already the case with LWcad previous releases when snapping features:
LW cad actually sees hidden geometries (in active layer or background).
With V5 and following and the new selection system this problem becomes really unworkable around, eg:
ctrl click empty space on screen selects all geometry, even what is hidden; when working on an heavy layer/object this turns into a nightmare. I believe I'll revert to LW 4.52 for the moment.
I think LW cad should comply to LW basics like what is hidden is non editable/reachable by the active tool(or snap option).
Victor, is it possible to have LWcad working like that at least in LW?
Thanks for your time.
