Booleans and DefeaturingA simple case to demonstrate primitives, Booleans, and how topology management can be used in conjuction with surface coarsening to remove features from a model. A tutorial video of this case is available on the videos page.
A box and two cylinders created with DGK.
After Boolean add and subtract.
Graded refinement applied to the upper surface of the box.
Merging surfaces with deletion of the feature curves and coarsening removes the indented cylindrical surface from the body.
Additional surface merging and coarsening. The circular curve is then split into four curves by creating topology vertices (all vertices highlighted).
Additional coarsening with a large size applied. The cylinder curves are allowed to be coarsened while the vertices are protected.
Our Xtl app, built on DGK, was selected as Desktop Engineering’s Editors Pick of the week for July 6 2011
