Dimensioning Torus

TSimna
I have a question about a measured torus hopefully someone can answer. This is also my first post here, so bear with me Slight smile. I've searched a bit but I haven't seen anything that answers my question. Basically, I need to figure out the minor diameter of this torus. If I hover over that feature in the Edit toolbar, under the ACTL measurements I can see the measurement i’m looking for (the .25027). I’m trying to figure out a way to dimension it or manually extract it using a variable or anything related to that. Any suggestions?

  • Neil,
    Using Feature Location to dimension a Torus with PC-DMIS 2020R2.

    Major diameter will use D = Prints the Diameter value. For an ellipse, this is the minor diameter value (same as H).
    Minor diameter will use L = Prints the Length (used for cylinder, cones, slots, and ellipses). For an ellipse, L gives you the major diameter value.

    Example:
    Feature name: B59_FTR1_NA
    Number of Hits: 9
    X NOM: 10.47
    Y NOM: 4.0599999
    Z NOM: 1.065
    I NOM: 0
    J NOM: 0
    K NOM: 1

    Major diameter: 1
    Minor diameter: .025

    Issue found when dimensioning the Major and Minor diameter:
    Using 2020R2 when I select the Torus feature within the Feature Location dialog window the D axis will be displayed in the Status Window.
    When I created the feature dimension for the torus I found the D axis is missing and the L axis nominal set at 0.
    I have too manually add the D axis to the dimension and add the nominal to the L axis.​​​​​​​

    Example is missing the D axis and the L axis nominal is 0.
