Macro sometimes (not always) errors at make file

Question asked by Shaun Jalbert on Dec 14, 2018

So I have the following macro which automates the "save as DWG" operation by also configuring specific options and then creates a directory to store the DWG file in.

This macro works 100% of the time when the "Export" folder doesn't already exist. But when the "Export" folder already exists, the script may run successfully, but sometimes, it errors out at the following line...



I can't figure out why it randomly works/doesn't work if the directory already exists. Is there a way to rewrite this to check if the directory exists, and if it does exist, to not make the directory, but instead use the sPathName? I'm just not fluent enough to write that out myself.
