Tip:
When entering distances or other parameters interactively, you can use a handy calculator built into in Revit. Prefix a formula with ‘=’ to envoke the inbuilt calculator.
Example: Copy a wall three times a given distance: In the Copy command enter pick the first point and instead of picking a second point simply enter =3*600. Results are the wall copies 1800 from first point. Revit calls this “entering a formula”. There are other formulas you can input:
Other examples:
| =1000+500 | result: 1500 |
| =1000/2 | result: 500 |
| =1000-500 | result: 500 |
| =(100*2)+300 | result: 500 |
