Dynamic fill dependent on line width

  • Dynamic fill dependent on line width

    This is a minor issue for most, I’m sure. While checking some custom column formulas that calculate area and perimeter of an ellipse, I created an ellipse and used dynamic fill to get an area measurement. I then compared that to the formula generated area and dynamic fill area was consistently lower (only slightly) every time. What I found is that dynamic fill fills to the edge of the line, not the centerline of the line and if you increase the line thickness, the dynamic fill area will decrease.

    On a side note, I asked ChatGPT to calculate the area and it failed miserably by using the wrong formula. I corrected it by providing the correct formula and it failed again. Then it stopped trying to calculate and just agreed with me. Maybe in a year or two……

    Try disabling your line weights. That will help Dynamic Phil find the correct boarder line.

      Set line weight to 0 point (zero)?

      That “Dynamic Phil” guy can be a bit fickle @troy-degroot 😎

      @dhwalkellc I noticed this issue a while back and haven’t used it much since. While I haven’t tried it with an ellipse I have experimented with a 10 ft x 10 ft square with various line widths. Each provides a different result – not the 100 sf that you would expect.

      When performing takeoff you need to be careful about the line weight of the source document as dynamic fill will always measure to the edge of the line, not the center.

    Admire your ability to check a formula and compare to Bluebeam quantity vs Chat GPT.

    Have you tried MS Copilot?

      Will take a look, thanks.
