Challenge: Draw box add chamfer and fillet with SOLIDHIST on without going mad

This is the desired object:

This is drawn with BOX (100,20,2), CHAMFEREDGE (2) on the four corners, followed by FILLETEDGE (1) on all edges on the top (8 edges because of the chamfer).

The above was drawn with SOLIDHIST=0, no problem.

The challenge is to do it with SOLIDHIST=1. In my hands it is pure agony. I wanted to detail the problems here, but they are so numerous it would take too much time.

Of course SOLIDHIST is nice because later I may want to change the size of the box, or the radius of the fillet, and the size of the chamfer.

For comparison, in another CAD package I did this same drawing (with solid history), with no problem, and in fact the drawing steps are absolutely unaltered by the presence of the retained history. This other product allows you to clearly see a selected solid and its history, and trivially make the changes to the solid and solid operation parameters.

Here is the example of this interface to solid history in the other CAD package:

You can see at a glance what operations make up the solid, and it is easy to change the parameters. In this example, in the drawing, because edge 3 is selected here, edge 3 is highlighted as well, so the chamfer offets for this edge are easily updated.

In summary, two questions:

 

  1. Can someone skilled in ACAD indicate how this simple drawing can be done in ACAD 2017 with SOLIDHIST=1?
  2. Why does ACAD not have an explicit view of the solid history of a selected solid. It is really tedious to have to click in the drawing to get the properties of a solid operation to show up in the PROPERTIES panel.
