How to identify selected line is straight or Curve?

Bhavik Sheth_21143

Hello Team,

I have used below function to select line.

*createmarkpanel lines 1 'Select line'the 
  set WCL [hm_getmark lines 1]
  *clearmark lines 1

After selection, I need to check whether selected line is straight or not.

Suggestion please how to proceed.

Thank you in advance.

Hello Bhavik

You can try the following steps : 

1. If a line is straight , the a center won't be created of this line type. In Hypermesh try to create a center node using straight line as an input and it would throw an error. 

2. In Tcl scripting, you can find the command that finds center node for an arc/circle from reference guide . The commands are :                                                                                                                    *createlist nodes 1 1 2
*linecreatefromnodes 1 0 150 5 179 

3. You can introduce an error handling using a catch command to check if the input line given as an argument to this command  causes an error or not .

*createlist nodes 1 1 2

curve_list = [list]

straight_line_list = [list]

if ([catch {*linecreatefromnodes 1 0 150 5 179 }] == 1) {

lappend straight_line_list $line_id # Find line id in your code

# Line is straight 

} else {

#Line is a curve

lappend curve_list $line_id # Find line id in your code

}
