Example 01 - Part lists with Collections and evalTcl()#

Part lists with Collections and evalTcl() postquery#

import hw

Example 02 - Interactive Selection with Default Settings#

Interactively querying Parts using custom context with default settings#

import hw

ses.new()
win=ses.get(hw.Window)
# Set Window to Animation
win.type = 'animation'
# Add Model
win.addModelAndResult(modelFile)

# Interactive Selection with default settings
inSel = hv.InteractiveSelection()
pCol=inSel.select()
print('')
print('Interactive Selection with Defaults')
print('-----------------------------------')
