Update: Full article describing this challenge can be read here:


Hello SOLIDWORKS Power-Users and welcome to the 8th WPUC!


For eternal glory and 1000 points, provide the best solution to this problem:


1. Download the attached file Eyeglasses-start.x_t

2. Import it in SOLIDWORKS

3. Solve any topological problems

4. Remove all the holes as per these pictures. Do not use sketches or curves!







5. The goal is to get as close as possible to the initial body geometry and topology, before the holes were added. Note that Surface Fill will not get you to the initial topology, since it will change the number of faces and edges.
