Hardscape Slab Thickness Change

[DanH]

I’m not sure how most people generate 3D object, but in our office we turn 2D polygons, rectangles etc. in hardscapes, then in the Object Info, under 'Draw 3D’ Go: 3D type > Slab. Then from there you can edit slab thickness, elevation etc. In VW 2016 you were able to set negative thicknesses to the slab. For instance: say you have a step at a height of -600 elevation then you set the step thickness at -150. You know the top of the step is at a height of -600 below 0 and then another -150 down to the next step, starting the next step at an elevation of -750. 

 

In 2017 it seems you can’t set a slab thickness of less than 0 anymore. Meaning, if I use the same example, if I have a step with an elevation of -600 (this you can do in 2017) and enter a thickness, I have to enter 150 to get the same effect however the elevation of the step will be -450 now. The next step after this one will then need to be -750 at 150 thickness to give it a height of -600. 

 

Doing this for all 3D Hardscape-Slab objects in a drawing becomes incredibly confusing and makes us question our accuracy at every change therefor slowing production down to a grind... 

 

Could we have this changed back to the way it was? 

 

Cheers,

Not sure if I understood the Problem right.

 

In Architecture we do our slabs directly from the slab tool,

from a polygon > create objects from shapes > slab or

fill bucket mode into closed wall arrangements.

 

I think negative thickness values aren't necessary as you now can set your

slab Z origin to top or bottom of the slab.

Hardscapes work differently to slabs: 

- they can be 2D only or 2D + 3D

- When the 3D is activated there are separate thickness parameters for the body and the border.  

- They don't have a Z value.  Instead they have an Elevation value which is relative to the Z of the Design Layer they are in.

 

The Elevation value is always to the bottom surface of the Hardscape object so to get the top surface at a required level you have to set the elevation value to the required value for the top surface minus the thickness.  Hence the wish by DanH.
