Civil3D Gravity Pipe Network creation and .ifc export

Описание: SEE THIS DESCRIPTION FOR MORE INFORMATION

This outlines one way to create a gravity pipe network in Civil3D (C3D) 2020 from CT Drainage and Drainage Profile plan sheets. I've tried a few different variations on building these, so this one method is just being presented to get your mind going. I suggest getting proper training (LinkedIn Learning address below) before you start. I also show some tricks to export it as an .ifc file so that it can be loaded into an AR viewer or other software, like Trimble Business Center (TBC) shown.

Please bear in mind that I am not even an intermediate Civil3D user. It isn't software that I typically need for my current role, as a supervisor. The current Gravity Pipe Network and IFC export in C3D 2020 is a little buggy and there are some areas for improvement even, in my opinion, on routines that work like they should.

Thanks to Christopher Fugitt, HQ Office of CADD and Engineering GIS Support, for helping with exporting and correcting the .ifc file. His modifications are below. As shown in the video, replace the appropriate 3 lines with these:

#24= IFCCONVERSIONBASEDUNIT(#25,.LENGTHUNIT.,'usfoot',#26);
#25= IFCDIMENSIONALEXPONENTS(1,0,0,0,0,0,0);
#26= IFCMEASUREWITHUNIT(IFCREAL(304.8006096012192),#27);

LinkedIn Learning if free to Caltrans employees and has a really good series on Gravity Pipe Networks. It is what I used to learn how to do this. It takes 4 or 5 hours to run through. Well worth the time if you are wanting to try this:
