around the area and then pressing
delete.
34
Polygon
Self-Intersection Removal

35. August 9th, 2016
• Make sure you get rid of small chunks in
the middle of your holes
• They will just create more errors later on
if it is not done
35
Polygon

• Try to make sure red squares
(intersections) are not too close together
or if needed, combine them
44
Parametric Surfaces
Potential Problems

45. August 9th, 2016
• It can be helpful to classify regions
based on what type of surface they are
• This can help the computer fit a surface
to it later
• The different colors represent different
surface types
• Ex: red=freeform, light green=plane
45
Parametric Surfaces
Classify Regions

46. August 9th, 2016
• Ctrl+A (to select entire part), then press
apply
• Red Surfaces need to be fixed
• Orange Surfaces probably should be
fixed

• Blue Collections
• Known radius (user-defined)
• 0.04” is a good radius
• If it doesn’t work, try changing radius
slightly up, otherwise change to
automatic
• If it still doesn’t work, change
classification to freeform
• Unknown radius
• Select Automatic
• Connection should be green
49

after them if the model is complete
• If not, continue to finish them up per
prior instructions
• Open: “surface-1.wrp”
