hello,

i saw all the questions in this forum, nice discussion.
i have one doubt with part instance.
manualy we can create part instance by part manager.
rename parts as duplicate, and ansa will ask , merge or make instance.

to make two different parts as instance, do we have any script API?

Hi Viswanathan,

Welcome to the forum. Yes there is a command to create instance from part.

Here is the description from ansa help.

MakeNewInstance, BETA PYTHON development Manual
NAME:
MakeNewInstance - Create a new instance of part or group
SYNOPSIS:
ansa.base.MakeNewInstance(PART, TRANSFORMATION_MATRIX)

DESCRIPTION:
This function creates a new instance of an existing part/group.
The position of the new created instance is controlled by a 4X4 transformation matrix.
Arguments

PART object the part object
TRANSFORMATION_MATRIX object a 4x3 list that describes the transformation matrix


RETURN:
The MakeNewInstance function returns a reference to the new instance or None in case of error.

EXAMPLE:
Code:
import ansa
from ansa import base

def main():
	# the example below, creates a new symmetrical instance of a part
	transf_matrix = ((1,0,0,0),
		(0,-1,0,0),
		(0,0,1,0),
		(0,0,0,1))
	master = base.GetPartFromModuleId("10")
	new_inst = base.MakeNewInstance(master,transf_matrix)

Don't know the exact python command for this. But you can do this in GUI. Open part manager, right click the part you want to find MI. Then Edit Tree> Detect Instances will do the job for you
If you find how to achieve this via python or betascript, please share it here.
