Hello,
I would like to copy catalog parts, specifically sheet metal parts (e.g., Simpson Strong-Tie), along an edge of a component. It works, but it only takes the part at its center of gravity. How can I set it up so that I can define a reference point of the catalog part as a reference? Best regards

Hi Holzi,
Can you show what you tried so far to get a better idea of what you are looking for ?

Hallo usai-sylvain

Attached is the code as I had envisioned it.

import element_controller as ec
import geometry_controller as gc
import utility_controller as uc
import visualization_controller as vc

def main():

ab_max = uc.get_user_double("Max Abstand (mm)")
off_vorne = uc.get_user_double("Offset vorne (mm)")
off_hinten = uc.get_user_double("Offset hinten (mm)")

elements = ec.get_active_identifiable_element_ids()
if not elements:
    return


pts = uc.get_user_points_with_count(2)
if len(pts) != 2:
    return

p1, p2 = pts
length = p1.distance(p2)
if length == 0:
    uc.print_error("Punkte dürfen nicht gleich sein.")
    return

richtung = (p2 - p1) / length

p1_off = p1 + richtung * off_vorne
p2_off = p2 - richtung * off_hinten
gesamt = p1_off.distance(p2_off)

if gesamt <= 0:
    uc.print_error("Offsets zu groß.")
    return

anzahl = int(gesamt / ab_max)
if anzahl < 1:
    uc.print_error("Zu kurze Strecke.")
    return

delta = (p2_off - p1_off) / anzahl

ref = gc.get_p1(elements[0])
neue = []

kopie0 = ec.copy_elements(elements, p1_off - ref)
neue.extend(kopie0)

for i in range(1, anzahl + 1):
    pos = (p1_off + delta * i) - ref
    kopie = ec.copy_elements(elements, pos)
    neue.extend(kopie)

ec.delete_elements_with_undo(elements)
ec.add_created_elements_to_undo(neue)

vc.set_active(neue)
vc.zoom_elements(neue)

ec.make_undo_available()
uc.print_error(str(len(neue)) + " Kopien erzeugt.")

if name == "main":
main()

Hi Holzi,

The reference point is the first element's P1 : ref = gc.get_p1(elements[0]). You could replace this by ref = uc.get_user_point() to let the user choose any point as reference :

# [...]
def main():
    ab_max = uc.get_user_double("Max Abstand (mm)")
    off_vorne = uc.get_user_double("Offset vorne (mm)")
    off_hinten = uc.get_user_double("Offset hinten (mm)")

    elements = ec.get_active_identifiable_element_ids()
    if not elements:
        return

    # get the reference user point 
    ref = uc.get_user_point()
    if not ref:
        ref = gc.get_p1(elements[0])

    pts = uc.get_user_points_with_count(2)
    if len(pts) != 2:
        return
# [...]

would that solve your problem ?
