About Design Rules
Design rules are guidelines for a design. They are based on the material type and the manufacturing process of a part. You can copy any number of design rule tables to a design, but only one rule table can be assigned to a part at a time. You can modify the rules for a design by changing the default values of one or more of the rules listed in the assigned rule table. The design rules and names are standard and cannot be changed, but they can be customized using relations.
A standard rule table includes the following elements:
Rule
Description
Default Value
Example
MIN_DIST_BTWN_CUTS
Checks the distance between two cuts or punches
5*T
1. 2T or 3T or Greater
2. Stock Thickness (T)
MIN_CUT_TO_BOUND
Checks the distance between a part edge and a cut or punch.
2*T
MIN_CUT_TO_BEND
Checks the distance between a bend-line and a cut or punch.
2.5 *T + R
Where,
H = Distance between the lowest edge and the hole
T = Sheet metal thickness
R = Bend radius
Min H = 1.5*T+R
MIN_WALL_HEIGHT
Checks the minimum bend height of formed walls.
1.5 * T + R
MIN_SLOT_TAB_WIDTH
Checks the minimum width of the slot.
T
1. Slot Height
2. Slot Width (T)
MIN_SLOT_TAB_LENGTH
Checks the minimum length of the slot.
0.7
MIN_LASER_DIM
For outer contour—checks if it has an arc with a diameter smaller than this value.
For inner contour—checks if it has an arc with a diameter smaller than this value and checks the distance between two parallel edges.
1.5*T
1. Outer contour arc
2. distance between 2 parallel lines
3. Inner contour arc
