Example

from hwx import inspire
from hwx.inspire import motion

model = inspire.openTutorialFile("Motion/M01_FourBar.stmod")
link = model.getChild('Link Single Slot')

tracer = motion.Tracer(
name='Tracer 1',
pen=link.features[0],
location=link.location,
color='Red',
thickness=2
)
analysis = motion.MbdAnalysis()
analysis.analyze()

getPoints(analysis, wrtPaper=False, startFrame=0)

Get tracer location at every frame of the analysis

wrtPaper - transform points into paper parts reference frame

getDrawPoints(wrtPaper=True)

Get points to draw if trace lines turned on
