Concrete surfaces question


Recommended Posts

Like a lot of operations, there's probably a few ways to do this. I think the roadway tools would probably do the job better (someone may jump in and advise), but you can do this with surfaces then shell

 

 

Taking your file..

3D poly by 3D poly, highlight and choose Model>3D Power Pack>Create Surface from Curves

 

with your concrete class set, you then get..

Note the red 'normal' arrow as this influences the shell command

 

Then choose the shell command tool with the appropriate settings - you wanted 0.2m

 

The slab is formed

This has formed in the correct direction. If the slab is shelled upward, either reverse the 'normal' arrow, or change the shelling criteria (inside vs outside) Then try again.

 

You'll find the larger sections of your roadway are more complex and VW divides it into many more triangulation parts.

Its just a matter of highlighting the various pieces and applying shell separately. Someone may jump in and point out a way to shell all at the same time.

 

Section-wise, you'll see the slabs are individual and don't merge at he 'touch' positions as they ought to. You could rectify this with a a bit of 3D tweaking, but I assume you don't need that level refinement.

 

Hope this helps.

I see you have added solids - not sure that has any bearing but this is my version of the same area (in your first file) and the section is complete

Maybe all areas were not correct before you added solids?

Just tried adding solids and it messes things up - I suggest you live with it as the geometry is not to VW's liking

 

I find I can add these...

and these...

but if I then add the two parts together it falls over.

 

I'm sure theres a reason, but I'd stick with what you've got 😎

so i made my surface with 3d polys snaping to plumb bobs

then offset the top surface by 300mm (as shown above)

 

then made a cube primitive subdivision

and snapped to all corners etc...

 

IF the subdivision tool had a few inhancements for the purpose of architectural concrete work...

1st would be to set it so all edges are sharp by default...THEN you do rounding later.

2nd would be to lock the top of the subdivision to a top geometry.

3rd break it up w/ control joints BUT the top surface always match so if you adjust one the mate will also move...

then you would have your core concrete tool...with no limitations

 

I know that vw shows off the subdivision tool by showing how it can make plastic chairs...

the reality is we work more with concrete then making chairs...

we should be able to do a whole parking lot or skate park with one big subdivision object or have it broken up at control joints...

the subdivision tool does the job! WOW! well done.

i found out how to set all my edges to sharp by right clicking. so issue #1 above is solved.

#2 above...i just used plumb bobs

note the section cut on the sheet.

also found a mirror feature that allowed me to work on one side only...WOW! what a time saver.
