What causes the following warning?
Error opening file: HandleView1.dwg
HandleView1.dwg is a file in the environment files (C:\ProgramData\Tekla Structures\xx.x\environments\common\symbols\) which is used to show the yellow handle when you select an object. This error is displayed if Tekla Structures is not able to locate or access this file. Usually reinstalling the environment and making sure you have access rights to the environment directories helps.
