Hi,

We try to get outline curve length. (outline curve mean highlight in picture)

Our solution is simple. 

1. create section

2. get section curve

3. get curve length

 

But, section curve have all curve.

We do not need inside curve (highlight in picture)

Please give me an idea if there is a better way.

 

Thanks, Wram Regards.

From the first solid feature get one edge green/white. If you feed this into this function this should  not include a contour from a cut feature.

 

extern ProError ProSmtedgeContourGet(
 ProPart		smt_part,
 ProEdge		edge,
 ProEdge		**edges );

/*
 Purpose:	Outputs an array of edges that form the complete contour of
		the entire green (or white) surface that contains the
		specified edge.

 Input Arguments:
 smt_part		- The sheet metal part
 edge 		- The edge (on white or green surface) that is
			 contained in the contour sought.

 Output Arguments:
 edges		- Pointer to ProArray of edges. The edges are
			 ordered exactly as for a regular surface contour.
			 The array will be allocated and filled by
			 Creo Parametric. Free it by calling ProArrayFree()
			 when you no longer need it.

 Return Values:
 PRO_TK_NO_ERROR	 - The function sucessfully retrieved the information.
 PRO_TK_BAD_INPUTS	 - One or more of the input arguments are invalid.
 PRO_TK_BAD_CONTEXT - The model is not a sheet metal part, or the
			 specified edge is not on the green or white surface.
*/

 

 

Proof it 😉

From a Tcl Console 

  1. Create a Selection Object
  2. Select an edge
  3. Extract the model item
  4. Get the model item id
  5. Get the smt contour based on the selected edge id

Green Edge was selected
Red is the highlighted output of the returned edge ids!

One option is to create an intent chain of the unbent model perimeter. Then create a curve copy of the intent chain. You can then use an analysis feature to measure the length of the outline curve.
