12d Model

I think for the missing strings. It seems like it was extrusions or non-formal colour playing havoc with the internal snippet workings on the Apply recreate function panel.
Lots of function deletes and copy left/right modifiers from a backup project. They cannot be open and the function deleted to ...

Hi Lee.
Was there an answer to Sam's issue? I am facing this same thing on data which did build in the first few instances of a Recreate being reapplied, however now a small section seems to not be built within the single line mtf snippet on the right modifier.
Where are my strings.jpg

I deleted ...

Hey Sam.
Didn't we need xml data because it had unique naming from the client and the dwg version of the same data had mini loops in part? From memory the dwg version failed to make cross sections all the way out.
What is the originating design software used? Give us a call if you like.

That is a part of my DNE to strings chain Paul which you have (and gave me the macros for).
You can see the pit string in cyan from the get edges macro runs the full external at the top RL attribute. However it doesn't take into account the top section.
The other issue is the Get Trimeshes from 12d ...

Generating trimeshes from 12d objects using a drainage network creates three mesh objects on haunched pits. This poses a problem when assigning object IDs which Kevin Sun has touched on in another post.
Trimesh Boolean Operations will 'join' two trimeshes together at a time. Is there a 12d panel ...

I have this issue too.
Received a new LiDAR DEM and there are over a billion points in it (insert Austin Powers gif here). Most of them are set at RL zero and useless but still take up space. Imported as a grid tin & string fine.
Tried to create a tin from the string and 12d crashed. Tried exploding ...

Darcy, you could pop in a Delete panel with source box set to Filter. Use View or Model(s) etc to isolate and include Extents tab with tick box 'Process only selected vertices', to isolate you -999 data.

So Generate Trimeshes from 12d Objects works. Resultant ifc file is mega huge (2Gb in this instance).

Thanks Graeme.
So my options are to either create boundaries and cut holes, which is not a simple process with shared tins, then export many tins to ifc. Or create boundaries and offset on the inside to trim the faces, add them to the retriangulate panel source.
The first option might create many ...

I am trying to create one export for Revizto using a supertin. The process I have so far is:
Create faces from supertin (bigfoot licence with LiDAR data)
Create new standard TIN using model from above
Tick: Weed tin Triangle data Colour by triangle data
Create ifc file using standard TIN ...

Hi Richard.
Have you checked this post:
viewtopic.php?f=3&t=13766

IFC from C3D worked in that instance. All objects came in as trimesh data. Check your header in the IFC file to see how it compares to the code in the above post.

12d needs a filter and delete option on some users out to push a buck.

To get the area it might be better to have the original strings (or you could use Get strings from trimesh edges) and create a TIN, or series of. Then use the Trimeshes from TIN tool and set the depth to 1mm or less. This way you can enquire the area on the trimesh and divide by two to get the area ...
