I believe you may have misunderstood what I was requesting.
If under Set-Up, Density...I input a density...I would like to set up a parameter (&density) to have the .prt density show up in the notes of my drawing. How do you set up a parameter to have the notes reflect the inputed value for density?
If you are working in mm the &density will show up as 0.00. If you want the density to show up as comparative to water you will have density=mp_density()/2.204623E-06, assuming you are in mm. I am in 2001, so the variables for Wildfire may have changed?
Regen the part from the beginning to make sure all variables have been filled. Use the model player and regen from beginning with Regenerate Features selected. Also density=mp_density*2.204623E-06 to convert to specific density. If you are working in mm, your density will be .0000nnnn or something like that.
Hora's solution worked. The problem was I didn't have spaces on either side of the equal sign. However, additionally I ran Utilities and Model Player and marked the Regenerate Features. Changed two variable at once.
I'm sorry it was such a simple solution and didn't know to have spaces on either side of the equal sign.
