Hello,

This is a work around for creating Simi parametric Mold Line Dimensions for a flat pattern drawing. (This does not work with "K" factors but does for Bend deduction)

1. Using ordinate dimensions that have broken alignment and hidden dimension lines, I place the dimension along with the bend note tag.

2. Depending on location I turn on the bend note tag leader line. ( my bend note file has the <bend-radius> tag commented out, I add it back when a part has multiple radius.)

3. This should be all I need but alas I have old school people I need to appease, so here comes the lame part. Lame because the dimension itself is parametric but the method is not.

4. To add Mold lines, add a limit tolerance of half your bend deduction value. So far this can't be linked to an equation. You can enter it as math in the tolerance field i.e. (.162/2) and it will calculate it when you exit the dimension properties.

5. Caution!!! because the limit values work fine for Vertical Ordinate Dimensions but have to be inverted for the Horizontal ones.

6. To do this type a negative # in the positive field and the positive sign in the negative field. (Lame I know!)

Let me reiterate that I'm no longer using this method because I've finally convinced the shop that the center of bend is our new standard.

From the trenches,

Jeff
