Prepare Pipe LineStock Parameter

Question

Hello, I'm not able to set LineStock Parameter with multiple values. If I use the following code, the BEND_ANGLE values are NOT set, and after this call, it is not longer possible to modify the line stock values in Creo manually. Technical Support seems not capable to give an answer. Here my Code, tk_linestockparam_Single_Debug() is an helper, code not here but the debug output.
 
For testing have an assembly open, including one linestock, the code uses the name MYLINESTOCK.
 
If somebody has an idea 🤗

Hello Jean Claude,I must apologize, I oversaw an eMail from Michael Wunder. He corrected my sample code, and this fixed the issue.It is required to tag the member with the same name. I checked it on extract, and got always a blank value. Now the code is working, thanks to support and Mr. Wunder👍  ProStringToWstring(LnstkParam.name,"BEND_ANGLE");LnstkParam.param_type= PROLNSTKPRM_MULTIPLE;for ( i = 0 ; i < 4 ; i++ ) {dVal = BendAngleVals[i];TK_DEBUG01 ("add value %6.3f",dVal);LnstkParamMember.name[0] = '\0';// It is required to tag the member with the same nameProStringToWstring(LnstkParamMember.name,"BEND_ANGLE");

Dear member,

Thank you for posting this question regarding LINESTOCK parameter file. As mentioned in the Creo Help documentation : "A line stock is a set of parameters that define material, grade, outside diameter, and other parameters of pipeline segments. Piping stores the parameters in the line stock feature. Before you create a pipeline, you must define a line stock. You can assign different line stocks to different line segments of the same pipeline because they may have different outside diameters, materials, and grades. Keep in mind that the system determines a pipeline’s physical (solid) shape based on the line stock from which it actually derived the pipe. You can edit line stock parameters using the LineStock dialog box, and you can add user-defined attributes to the list. You can also read and write a line stock to a .stk file. You can set up a library of line stocks that you can retrieve to route a particular pipeline. "

Regarding the User defined parameters BEND_ANGLE is a valid parameter with MIN_BEND_ANGLE and MAX_BEND_ANGLE

Please review Creo Help for Line Stock Parameter Files and Report Table Parameters Applicable to Piping and let us know if this help.

Best regards

Jean Claude
