Tube command 3d parts not aligned

[Piotr Dobrowolski]

I am creating an object that will be a parametric car ramp using a tube command as a base of geometry. The geometry is then cut to parametric outline in plan to fit the needed geometry.

And I found out that tube command (1st or 2nd) is buggy as hell with alignment of the geometry parts.

It is not visible from the outside, but doing a section reveals the "secret". Easy to check with the railing tool with the profile of the slab 3m wide with 2 layers one finish - 5cm and base - 20 cm.

The left is a non cut one the right is using the cut to fit the outline.

Plan i rotated 90 deg from what is seen in 3d

Here goes the section of the non cut one:

The outside is aligned...but not what happens inside.

But when it is cut it becomes even "funnier":

Any fix of this command is on the "go"?

It is very usable in many cases.

For finishing the tool I have on the workshop I will probably need to do a series of bolean operations which will slow down the model...or I will give the advice to use single, non composite slab...which sounds no good.
