This function is used to check the contact between reference blank (copy from binder) and punch during drawing. Click this button to display the Contact Check dialog box illustrated in Figure 7.2.36. Copy the existing binder in the position of the initial contact between blank and punch as reference blank and move the reference blank along the stamping direction, as illustrated in Figure 7.2.37.

FROM CONTACT
The distance between reference blank position and the initial contact point.
FROM CLOSED
The distance between reference blank position and the closed position.
DRAW DEPTH
The maximum draw depth between binder and punch. When the die and punch are closed, take the first contact point of reference blank and punch as the reference point. The maximum draw depth is obtained by calculating the draw depths between this reference point and all points on the binder.
