Hello FME 亚搏国际在线官网Community,
I am working on a project where I need to convert an AutoCAD .dwg file into Apple's Internal Mapping Data Format (IMDF).
The tutorial FMEprovidesassumes you have amaster drawing file.Being that I was not able to find a master drawing file for the space I am looking to model,I created my own AutoCAD file.I amnota Civil Engineer and Ido nothave experience in AutoCAD.
I wanted to know what steps I can take to actually modify the AutoCAD file such that FME will process it correctly and spit out the .geojson file I need to proceed with IMDF.I've heard certain terms like blocks,block attributes,layers,and properties but I don't know what exactly to do so that FME will read features out of the file.
If anyone is willing to share information or even resources that might put me on a better track,I'd appreciate it greatly!
Thanks!
Hi@bsalgado98,
The master drawing file is used to more easily align building levels that may have been drawn individually,without referencing the other levels with respect to position.It can be a new file you create for this purpose,then Xref the other files into.
CAD is likely the hardest data to properly convert to IMDF,since it allows a great deal of latitude in the presentation and topology of the features,and IMDF is pretty rigid in its requirements.If it is available,I strongly recommend getting a Facilities Management version of the CAD data,since it is more likely to be in a structure more compatible with IMDF than architectural drawings.
I will contact you directly to talk to you about the specifics of how FME can help with your conversion.
