Daljeet Singh has helped me a lot on this subject. If anyone else even encounters this matter as a question, here's further information:
- first, without entering into drafting environment u can directly write a text in manufaturing environment. (Menu Bar - Insert - Note) (Quoting Daljeet Singh)
-The reference sets he talked about:
1. Menu Bar - Format - Reference Sets...
2. Either select one of the existing sets or create a new one.
3. Select the notes you want to have shown in the assembly.
4. In the assembly, go to the assembly navigator (the sidebar).
5. Right click on the relevant part.
6. Click on "Replace Reference Set".
7. Click on the reference set that contains the notes.
If you've added the notes to the reference set "MODEL", it's possible the notes are already visible when you've added the notes to the set.
-To engrave a text as one line, it's best to use one of the 1 line thick fonts (don't know which ones are, but I know there's one).
-If you want overlap in your engravement (when starting point and end point are the same, a small bump might be visible), you can use the "Planar_Text" operation.
I don't know how to engrave lines on their own yet but if someone encounters, please share with the rest.
