Actually copying the parameter number seems like it is an unnecessary step. What is your parameter name that contains the 11 digit part number (side note: do you use Intralink?). Is there a reason why you do not want to create a drawing template instead of starting with an empty drawing? It will be a lot easier than using a bunch of mapkeys to create a new drawing every time. From what I gather you want, this is what I would do.
1) Create a new part
2) Have a mapkey to insert all parameters related to that part. eg (copy into config.pro with text editor)
mapkey am1 @MAPKEY_LABELAdd Model Parameters...;\
mapkey(continued) ~ Activate `main_dlg_cur` `Utilities.psh_params`;#PART;#CREATE;\
mapkey(continued) #STRING;PART_NO;<EMPTY_STR>;\
mapkey(continued) #STRING;WEIGHT;<EMPTY_STR>;\
mapkey(continued) #DONE/RETURN;#DONE/RETURN;
3) Modify parameters (you can again create a mapkey to modify these)
mapkey am3 @MAPKEY_LABELModify Model Parameters...;\
mapkey(continued) ~ Activate `main_dlg_cur` `Utilities.psh_params`;#PART;\
mapkey(continued) #MODIFY;#PART_NO;\
mapkey(continued) #MODIFY;#WEIGHT;#DONE/RETURN;#DONE/RETURN;
You should now have a complete model with the drawing number parameter, &PART_NO, that contains your 11 digit number
4) Create a drawing FORMAT (you can search for more information on how to do that) and use a table in the format to display parameter. Type "&PART_NO". Should display the 11 digit number when a model is inserted in the drawing with that format. This format also contains things that you don't want to edit in the drawing once inserted. For example, the border and other model parameters.
5) Create a new TEMPLATE with the 3 views placed. You can use a note here if you would rather to bring in the model parameters.
6) Then with a new part, create a new drawing from part using the TEMPLATE with the FORMAT and all parameters, borders and views should be defined. It requires a little more prep work, but probably a more stable method than mapkeys doing everything.
How does this sound? Hopefully this all makes sense.
