Do away with manual alignments - use Readpoint

Hi Everyone
I am fairly new to PCDMIS being a Mitutoyo programmer for the last 10 years (Booo). The training I had on PCDMIS was reliant on a MANUAL setup before going into DCC mode. By going straight into DCC mode position your probe over its start point. Then you can insert a READ POINT. Then put the XYZ origin on the READ POINT and hey presto your probe has a X0, Y0 and Z0 starting point. You can now do a rough setup by getting the CMM mode to search for your part elements.
This can still then be skipped if not required for further parts. Why go to the lengths of manual probing when the CMM will do it for you?

I am enjoying the new challenge of PCDMIS and can see that it is deep and dark. By using code instead of set routines like the Mitutoyo I realise it can be a lot more flexible. Now if I only knew all the codeing tricks?
Please look out for my questions appearing.

Here is a snipet of code that is in all our programs. We have a plate that lets us repeat positions very well from one part to the next (similar to leaving a square permanently clamped). This takes care of the manual alignment, and you can do a pair of DCC alignments to get it done. If you comment out the GOTO/ENDOF_FIX_ALIGN before you run, you can set the part anywhere and it will go back to that spot on subsequent runs.

The Move/point after the Fix_Align is to get the probe in position to rotate safely.
