The command ADDSLOPEPATTERN was developed to expedite the creation of the Slope Pattern of the Civil 3D corridors.
In very large corridors, adding the Slope Pattern can be very time consuming and Plus, Civil 3D's performance drops dramatically when it needs to rebuild.
Thinking about it, this command speeds creation. To do this, it adds Slope Pattern between codes N1-N2, N3-N4, N5-N6. .. Created in the subassemblies of daylight. Note that these codes are only implemented in subassemblies created by TBN2NET subassemblies.
The addition of these slope patterns is recommended only at the end of the modeling, since
which reduces performance.
But if you added them and noticed a lot fall
performance, remove the slope pattern with the REMOVESLOPEPATTERN command.
