I’m happy that helped.
A couple of additional things before you get too far into this.
Create a suitable template for your work. Include things like specific layers for SU viewports, LO drawing entities, dimensions, text, etc. Dimension and text layers should be higher in the Layers list than the layers for viewports and other drawing stuff. Otherwise the text entities will wind up behind the viewports and stuff. You can also add stuff that would be the same from document to document like page numbers, borders, title block, etc. Make settings for text entities (font, size, dimension arrow style and line weight, label leader arrow style and weight, etc.) also choose the paper size, maybe turn off grid snapping if you don’t want that (Arrange menu). Then Save as template for later use.
Make sure you put your various entities on the appropriate layers as you work and lock layers you aren’t working on to prevent changing things you don’t want to change.
