Issue:

• When I convert my model to an implicit body it is creating artifacts and fragmented pieces. 
• My part has gaps where they were none
• My part looks smaller than the original part

Cause:

This can be caused by a few things, some of the most common are:

• • Tolerance too low
  • Errors in mesh/unclean mesh
  • Errors from CAD
  • Resolution too low
  • Thin Implicit

Solution:

• • If your tolerance is too high, change it in the block where you are converting it to an Implicit body. This will re-calculate and should get rid of any artifacts. 

• • If this doesn't improve your part, another method is to convert it to a Mesh. Sometimes the artifacts will disappear in the mesh.
  • Unclean Mesh: The incomplete look may be caused by meshing errors, creating artifacts. Try using the Split Mesh block to separate out the small, fragmented parts. 
  • Converted a surface to an Implicit: Thin implicit bodies don't show up well graphically. Add a thickness to your part by using the Thicken Body block to show a more accurate result.
  • Ran a process and it looks odd: You may need to increase the resolution of your viewport by clicking the menu in the lower-right or using the hot-key CTRL-H to take a high-resolution snapshot of your part.
  • The part has gaps where they shouldn't be any: Use CTRL-H to see a high-resolution image and see that there aren't any gaps in the implicit, it is just how it shows up graphically.
