MOLDWIZARD NX6 - cannot set tap drill dia on auto screw

[UNIFORMSRL]

Hello everybody! For CAM reasons, I am trying to adapt the tap_drill_dia parameter of auto screws to our bore standards.
I am not able to change it though: everytime I change the parameter (for example, from the standard part window) it seems to adapt itself to the thd_metric.dat value... Even if I have changed that table!

Have you got any hint about it?

I mean, fron where does it read the TAP_DRILL_DIA parameter?

I have customized the DME manual shcs component so that I can swich it from inch to a metric screw within the same part (useful for screws in default assemblies when some customers require metric, and some inch screws).

Anyway, I have attached the xls file driving the screw component. You can see the tap drill is pulled from VAR part (under your TOP assembly) by default, and I entered it mannually for the metric sizes.

Thank you very much,

I have noticed before that the tap_drill_dia was pulled from the var file. That's why I have customized the var file (see picture attached). Still, I cannot keep the change I have done. For example, if within the var file I have a value of 10.2 for the M12 screw, the value on the screw is always 10.5792. I do not understand where this value comes from.

Have you checked the xls data file driving the component? It may be like mine, as I show some screw sizes referencing the var file and some (the metric sizes) being hard coded. I did that because we use inch drills instead of metric, and it was an easier mod than trying to figure out the var and dat files.

Also the excel file has been customized (see picture attached). I suspect there is some macro in Moldwizard running under, which changes the tap_drill_dia to its original values.

I see. There are some knowledge fusion references there that I havent seen before, so this may be more involved than I'm familiar with.

Just to clarify, there is an expressoin TAP_DRILL_DIA in the screw component, and it does NOT match
a) the driving xls file (M12=10.2 in your picture),
b) the VAR file (M12=10.2 in your picture), or
c) the thd_metric.dat file (M12=?)

Is that correct? What value are you getting?

Hello again! It does not match anyone of them. The value I need is 10.2, the value I get is 10.5792. Take into consideration that I have customized a), b) and c). So there must be another place it takes that value from!

I'm afraid I'm out of ideas, may be time to call GTAC.

OK, I found out!!!

Standard threads for Moldwizard screws are place under the library of moldwizard, in the "templates" folder. It is an excel file named thread_standard_dat.xls

Thank you very much for your help, in any case!
