Re: Trimesh End Caps

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 ...

Re: Trimesh End Caps

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 tha...

Re: Trim Tin

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 explo...

Re: Convert Super Alignment to Super String - Null Points

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.

Re: Export Super tins

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

Re: Export Super tins

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 su...

Re: Export Super tins

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 model Super...

Re: Importing DWG pipe network

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.

Re: cut/fill

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

Re: Area of a trimesh face

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 ...

Re: Group Vertex Attributes

Hi Nick. Same way with the manipulator but here / is your friend, like grouping in names.4d to create sub groups: "Electrical/HV/Poles" as an example. 1 in the vertex box gets the first vertex only, 0 gets all vertices on a string. Have you tried the stylesheets I posted up in the surveyin...

Re: Survey mapfile based on point attributes

Hi Nick. Have you tried the attribute manipulator to fix your point problems? Can set it up and then run in a chain like the mapfile. A little tedious to setup but it seems this may replace mapfiles soon. Also good to catch all items in a filter from the panel window to apply rules to. I copied and ...
