FormZ is weak in this area, imho especially for something like a cylinder where snaps do not work to it's 'rectangular view' extents. No joy here with independent scale or transform, and the end of the cylinder is obstructed by the wardrobe side, and hiding the side isn't much help to do a reshape because after I unhide it, reshape becomes inactive. The best I can manage is to reshape the rail through the side, then section cut the rail with the face of the side as a cutting plane and delete the excess. It works but could be simpler.
We really need a better, more tangible selection rectangle which could assist here.
[The selection rectangle ideally could be adjusted so that its 'catch' can be fine-tuned.]
When selection is complete I would like the selection rectangle to be able to be scaled, like in so many other softwares, so its extents can snap to something.
I also wish we could snap to the top or bottom of a cylinder edge when in orthogonal view instead of to a segment which is unlikely to be at its precise X or Y limits.
I am finding adjusting the lengths and position of wardrobe hanging rails to fit their spaces which should be a very simple operation from a front view in wire frame is a lot more time consuming than it should be. Scaling of a selection in Turbocad works well, hopefully FZ can soon improve in this area. I wish I could roll all the good features of several programs into one, this feature needs looking into unless I am missing something obvious, as in Turbocad I could adjust these hanging rails very quickly indeed without resorting to a boolean operation.
