When a manual point is being taken in LK-DMIS a check is made to see if it really is a touch by examining the touch vector. If 0, then it is not a touch.

John wants to get a point and not move the machine which will fall foul of this problem and produce the error message "touch direction has zero magnitude vector".

A way round this is to use the statement MEAS/POINT,F(label),0 which causes the CMM to record the current position. In conjunction with a TEXT/OPER you can cause the CMM to stop and prompt you to place the probe in a hole, when you click OK, the current position of the probe is recorded and you can then make it a datum or whatever.

We are considering removing the check in a future release.
