Hello all,

I'm converting CAD data and I'm receiving this error code:

Postcondition failed at topology.cpp:1089. Expression: remainingLRP != nullptr

I'm thinking that it is caused by bad CAD data. Has anyone seen this error before?

Also, I'm just looking at Walls (for the moment), but when I translate the data, doors from the door layer come through. Does anyone know what may be causing this?

Thanks, David

Hi @david_prosack88 ,

 

Sorry to hear you are receiving this error code. It is not a super informative error. Would you be able to share your workspace, log file and/or data? This will be helpful in trying to help figure out the error.

 

If you cannot share your data here, please submit a problem report here.

 

Thank you!

 

At which point during the translation does this error message pops up? While at writing, try to use a GeometryValidator to filter and correct the data before writing them to (another?) format.

Hi @verdoodtdries,

 

 

I re-ran the the workbench and added just walls to the workbench and received an "Error running translation" with it failing at the dissolver transformer. I also received multiple warnings before it failed saying, "a point was encountered that was enclosed in more than one polygon." I do not see any points in the CAD the drawing.

 

 

Thanks!

Hi david_prosack88 ,

 

Can you provide a template workspace of the issue you want to solve. The points in FME are not automatically autocad_points. If you are e.g. using autocad_blocks these autocad entities can be read as points in FME. It all depends on your reader settings. I think your error message is due to the facts that you're providing input in the Dissolver transformer that can't be dissolved.
