Objective:
I need to change the thickness parameter for my IFC export, it defaults to a radius of 3.
Resolution:
1. Open the IFC file in a text editor (e.g. notepad)
2. Navigate to the parameters called "IFCCIRCLEPROFILEDEF"
3. Change the final value within the brackets on this line to the desired radius, then save and reimport the file into BIM Vision
For example: change "IFCCIRCLEPROFILEDEF(.AREA.,$,$,3.);" to "IFCCIRCLEPROFILEDEF(.AREA.,$,$,0.5);" to change the radius value from 3 to 0.5.
