I wrote this code to the following question:
code:
import maya.cmds as mc
mc.window()
mc.columnLayout()
mc.button ('make chain', command="chainspheres(),chainpc(),chainpp()")
mc.button ('make joints', command="jts1(),jts2()")
mc.showWindow()
def chainspheres(): # Chain Spheres
#Make sphere 1
mc.sphere(n='sphere1') # Create sphere with name sphere1
mc.move (0,0,0) # Move sphere1 in positions
mc.makeIdentity( apply=True ) # Freeze position
#Make Sphere 2
mc.sphere(n='sphere2') # Create sphere with name sphere2
mc.move (5.213,0,0)
mc.makeIdentity( apply=True ) # Freeze position
#Make Sphere 3
mc.sphere(n='sphere3') # Create sphere with name sphere3
mc.move (10.134,0,0) # Move sphere1 in positions
mc.makeIdentity( apply=True ) # Freeze position

def chainpc(): # Chain polyCube 1
mc.polyCube(n='cube1') # Create pCube 1
mc.move (12.714,0,0) # Move sphere1 in positions
mc.makeIdentity( apply=True ) # Freeze position
mc.polyCube(n='cube2') # Create pCube 2
mc.move (14.885,0,0) # Move cube3 in positions
mc.makeIdentity( apply=True ) # Freeze position
mc.polyCube(n='cube3') # Create pCube 3
mc.move (16.933,0,0) # Move cube3 in positions
mc.makeIdentity( apply=True ) # Freeze position
mc.parent( 'cube3','cube2', relative=True )
mc.parent( 'cube2','cube1', relative=True )
def chainpp(): # Chain polyPlane
mc.polyPlane(n='plane1') # Create pplane 1
mc.move (12.714,0,2.055) # Move sphere1 in positions
mc.makeIdentity( apply=True ) # Freeze position
mc.polyPlane(n='plane2') # Create pplane 2
mc.move (14.885,0,2.055) # Move plane3 in positions
mc.makeIdentity( apply=True ) # Freeze position
mc.polyPlane(n='plane3') # Create pplane 3
mc.move (16.933,0,2.055) # Move plane3 in positions
mc.makeIdentity( apply=True ) # Freeze position
mc.parent( 'plane3','plane2', relative=True )
mc.parent( 'plane2','plane1', relative=True )

def jts1():
# Make joints in geometries polyCubes
cmds.group( em=True, name='pcube_grp' )
cmds.joint (n='jtcube1')
cmds.delete( cmds.parentConstraint("cube1","jtcube1"))
cmds.joint (n='jtcube2')
cmds.delete( cmds.parentConstraint("cube2","jtcube2"))
cmds.joint (n='jtcube3')
cmds.delete( cmds.parentConstraint("cube3","jtcube3"))
# Delete Geo
cmds.delete ('cube1')
def jts2():
# Make joints in geometries polyPlanes
cmds.group( em=True, name='pplane_grp' )
cmds.joint (n='jtplane1')
cmds.delete( cmds.parentConstraint("plane1","jtplane1"))
cmds.joint (n='jtplane2')
cmds.delete( cmds.parentConstraint("plane2","jtplane2"))
cmds.joint (n='jtplane3')
cmds.delete( cmds.parentConstraint("plane3","jtplane3"))
# Delete Geo
cmds.delete ('plane1')
# END
The question is:
When .... I create the geometries on the Make Chain, the geometries
appearance in the viewport ok? suppose I want to delete the string
(plane1). Apart from that, squeeze the button Make Joints.
An error occurs:
# Error: Object is invalid plane1
How do I recognize the script that plane1 was deleted manually without
the error occurs?
