Hello good day, I make the suggestion to add guide lines, these guide lines would be to improve the precision and fluidity when drawing in the 2d section, the position of these would be to drag them from the units ruler, a clear example as in the programs from Gimp or Inkscape. (And that these guide lines are in a different color and dotted so as not to be confused with the drawing). But without forgetting that the guide lines have the same function as in those programs, the function of magnetism at intersections.
I would love this. I come from Sketchup and what I find difficult in SD3D is its snaping does not work as expected. I expected i could snap to wall borders, but it does not (I have the option enabled). It snaps to something sometimes but I cant find it snap to what i move it near to. Guide lines could solve this.
