Macro to export GD&T and "separate" them

[zwei]

I am trying to figure out way(s) to separate the GD&T Exported into the following format

1: GD&T Symbol
2: Tolerance 1
3: Tolerance 2 (if any)
4: Primary Datum
5: Secondary Datum
6: Tertiary Datum

Take the following example :

I had tried a few approach but i cant figure out a proper way to separate them (especially for tolerance 1 and tolerance 2 value)

Method 1: GetTextAtIndex
Result:

GetTextAtIndex(0) = <GTOL-POSI>
GetTextAtIndex(1) = <MOD-DIAM>
GetTextAtIndex(2) = 0.4
GetTextAtIndex(3) = <MOD-MMC>
GetTextAtIndex(4) = A
GetTextAtIndex(5) = B
GetTextAtIndex(6) = <MOD-MMC>
GetTextAtIndex(7) = C
GetTextAtIndex(8) = <MOD-MMC>

Method 2: GetFrameValues+GetFrameSymbols3
Results:

GetFrameValues(1) = 0.4,,A,B<MOD-MMC>,C<MOD-MMC>
GetFrameSymbols3(1) = <GTOL-POSI>, <MOD-MMC>, , , <MOD-MMC>, <MOD-MMC>)

So far i am able to use the GetFrameValues+GetFrameSymbols3 method to get all field as string except Tolerance 1
and Tolerance 2

Any1 is able to help?

Can you be more specific as to what you're referring to as "Tolerance 1" and "Tolerance 2"? It's a bit unclear from the information you've given.

If it's referring to the standard +/- tolerance on the actual dimension, you can obtain that through IDimension.Tolerance. If it's referring to something else, please point us in the right direction.

See example below.
Tolerance 1 is diameter 0 @ MMC
Tolerance 2 is dia 0.05 max

The solidworks documentation for GetFrameValues shows that the return values are as follows:

Format of return array of strings is:

retval[0] = Tolerance 1
retval[1] = Tolerance 2
retval[2] = Datum 1
retval[3] = Datum 2
retval[4] = Datum 3

The returns for GetFrameSymbols3 is:

retval[0] = Geometric tolerance symbol
retval[1] = Material condition symbol for first tolerance value
retval[2] = Material condition symbol for second tolerance value
retval[3] = Material condition symbol for datum1
retval[4] = Material condition symbol for datum2
retval[5] = Material condition symbol for datum3

There are empty values in the return arrays that you posted that should be filled with the tolerance2 information if that field is filled out. I'm not able to code an example to verify this right now though.

It's interesting that they split these up like they do. For the tolerance values, it looks like you have to interrogate GetTextAtIndex manually. I whipped this up and ran some tests, see what you think

Sorry for the poor format. I just ripped and butchered the Help example with no mercy.

It's interesting that they split these up like they do. For the tolerance values, it looks like you have to interrogate GetTextAtIndex manually.

The tolerance values are in the array returned from GetFrameValues. You have to use this along with GetFrameDiameterSymbols and GetFrameSymbols3 to get the full picture.

A symbol like this:

outputs a set of data like this:

Code: Select all

Frame 1 start
	================== Has Diameter Symbol =================
	True
	True
	================== Frame Symbols =================
	<GTOL-PERP>
	<MOD-MMC>
	<MOD-LMC>
	<MOD-LMC>
	<MOD-MMC>
	<MOD-LMC>
	================== Frame Values =================
	0
	.05 MAX
	A<MOD-LMC>
	B<MOD-MMC>
	C<MOD-LMC>
Frame 1 end

The LMC/MMC information associated with the datums appears in both the results from GetFrameSymbols3 and GetFrameValues. The whole IGtol API seems like it was programmed by comittee.

I hadn't noticed GetFrameDiameterSymbols...nice!

Where I think the trouble lies is determining where the modifiers are in the frame (specifically, tolerance 1 and tolerance 2). I know I was overthinking it, though.

Nice!

Just one last question... using GetFrameDiameterSymbols seem to return TRUE for both cylindrical and spherical tolerance zone, is there anyway to determine whether it is a cylindrical or spherical modifier (<MOD-DIAM>0 vs <MOD-SPHDIA>)?
