relating a manual input in a region

[RL_10410177]

I am using Creo Parametric Release 4.0 and DatecodeF000

I'm trying to make a .frm to use as a base sheet for multiple drawings. There is a section where some data will be manually input like height, weight, and length, and I'm trying to find a way to make other squares on the table auto spit out the metric version of the input data.
For instance, I would manually input 50 (in) into the length and the table auto fills the square next to it with 1270 (mm).
Alternatively, if set up parameters so the table would grab the weight (lbs) and then auto calculate the weight (kgs).
I get that I need to use relations to do this but I'm unclear on how to do the relation.
Thanks in advance.

Hi,

the mentioned functionality cannot be defined in the Drawing/Format mode, because these working modes do not enable to define relations. You have to define parameters & relations in Part mode and call these parameters in table cells.

What if I made the weight a parameter of the part, could I then set up a formula in the table to pull that weight and convert it to metric?

[TomU]

Yes, but the approach changes slightly if this is a single part drawing or an assembly drawing.  Either way, a repeat region will be required.

[RL_10410177]

That would be fine, I've got other repeat regions in my template as well. This would be for an assembly drawing but would only be pulling the weight from the top level part. my parameter is lable "WT", and I've tried creating a repeat region with &WT/2.2 but that just shows up as VALUE/2.2. How do I get the region to treat it as a formula?

[TomU]

See attached assembly.  (Creo 9.0)

[RL_10410177]

I input your formulas exactly as you wrote them but my table came back blank. I'm using creo 4.0, could that be why?

[TomU]

When you entered the values in the table rows, did you type what you see above or use the picker?  The text above does not show the leading "&" that must be present in each cell.

[RL_10410177]

Here is what I put into the template form:

And here is what shows up when I apply it to an assembly drawing,

Notice on TomU's, anything defined in the repeat region relations don't use asm.mbr.xxx, they use &rpt.rel.wt_kg

[TomU]

Yep, what @StephenW said.  From your picture above, you would need "&rpt.rel.WT_KG" entered in the table cell.

Just to test it, hard assign a value outside the IF statement in the relations.

WT_KG = 12345

[RL_10410177]

on the template:

symbol on the drawing:

still blank. didn't pull the hard value either:

Thoughts? I really appreciate yal'll helping me with this. 

[TomU]

It sort of looks like only that one cell is your repeat region.  It's going to be much easier to troubleshoot if you have some additional columns in the repeat region for debugging.  Add "&asm.mbr.name" to one column and &asm.mbr.WT" to another, just to see what kind of inputs you're getting to the relations.

[RL_10410177]

table with more columns:

that created a whole bunch of rows this time, not sure why.

here's the region attributes for reference:

[TomU]

Please use &asm.mbr.name in one of the columns, just for now...

does every part have a parameter in the part called wt? I think that is problem one

You can use the system weight parameter PRO_MP_MASS instead.

You may want to download TomU's zip file on his original response.

There are several things I see in your table. I assume you are working in a drawing with an assembly as the model and that model is the active when you are creating this table.

The first cell, you are calling the weight as just a parameter cell, not in the repeat region. To use the relations, I think you need the weight used in the table.

Add in the name using asm.mbr.name first with no relations to make sure you get a table generated, then add  in the weight so that shows (still no relations)

Then add in the relation and the callout for the relation. I think you are fighting multiple problems and haven't ever gotten a basic table started.

[RL_10410177]

I kinda got it to work with rpt.rel.wt_kgs using this relation:

I say kinda since there are some blanks for some reason.

So this is great for a BOM table, but I just want it looking at the top level. Would I need an if statement to single it out?

[TomU · Accepted solution]

You're options are a little limited with Creo 4.0.  There are some extra repeat region parameters that have been added to newer versions of Creo that make referring to the parent model easier.  Regardless, here's how to do this:

Table Cell:  &mdl.param.value

Table Filter:  &mdl.param.name == WT

This will create a single cell repeat region that only displays that one parameter value from the active model (when the repeat region was created.)

Once that's working, you can add additional relations to manipulate the value of WT however you want and return something else.  Just remember to change the cell value to refer to your new custom parameter inside the relations.  (&rpt.rel.WT_KG or whatever.)
