When placing center marks in slots, I use the following tool:

But this keeps happening:

Is there a way, or setting, or something that is causing this?  It's getting mighty frustrating to drawings with this program as it seems to have many quirks such as this that is causing mo to have to constantly redimension the same part over and over again, as this, and other errors constantly seem to plague every drawing done.   Almost every view seems to lose dimension references when using these tools that are supposd to make things faster.  Most of my drawings are done using weldment soildparts, so I don't know if that is the primary cause of the issue, or if there is some settings that are causing this, or the program is just  that unstable.
