Title: Periodic flag in a spline doesn't match periodic value shown in properties?
Post by: V@no on April 27, 2024, 09:59:59 AM

I've been playing around with group 70 (https://help.autodesk.com/view/ACD/2023/ENU/?guid=GUID-E1F884F8-AA90-4864-A215-3182D47A9C74#GUID-E1F884F8-AA90-4864-A215-3182D47A9C74__WSFACF1429558A55DEC759DDFFB0EBA947-4A9F) of a spline and noticed that "periodic" bit (bit 2) could be set, but spline's properties panel shows it as not set:

Code - Auto/Visual Lisp: [Select]

1. (logand (cdr (assoc 70 (entget (SSNAME (ssget ":S" '((0 . "SPLINE"))) 0)))) 2)

Why is that?

Thanks.

PyRx shows False

Code - Python: [Select]

1. import traceback
2. from pyrx_imp import Rx, Ge, Gi, Db, Ap, Ed, Gs
3.  
4. def PyRxCmd_doit() -> None:
5.     try:
6.         db = Db.curDb()
7.         es = Ed.Editor.entSel("\nPick it: ", Db.Spline.desc())
8.         if es[0] != Ed.PromptStatus.eOk:
9.             raise Exception("Oops {}: ".format(es[0]))
10.         sp = Db.Spline(es[1])
11.         print("isPeriodic= ",sp.isPeriodic())
12.     except Exception as err:
13.         traceback.print_exception(err)
14.
