That is a different issue. The install media is 5.2 gb, yet the actual installed files for autocad is 2 gb or so.
I installed c3d so deselected the c3d, map, and inventor server folders.
So what is the extra 3 gb in the install media?
1/2 gb in 3rdParty
1/2 gb in Content (materials)
under x64, its:
1 gb RC2018 (recap install files) Can you believe it?
.4 gb en-us
.4 gb Components
So likely the materials got installed, bringining the installed size to 2.5 gb, and also some drivers and things, bringing it to maybe 3 gb.
The install media seriously has Recap in it, what a joke. wow, the sample dataset is 1/3 gb in there.
They did that because they force you to make .rcs files from any point cloud files (.las and .laz) before you can bring into acad.
