  • if one uses Fusion, the vector lines are not necessarily joined. So, after extensive time in Rhino and in the Apire software, and with Nathan's help, it eventually started to look more correct.

  • I brought this design into Aspire to build my cut paths, and ran into all sorts of problems with joins. Even though Fusion recognized that I’d built a series of closed shapes, Aspire did not, and just saw a bunch of segments. I cleaned up my contruction lines and reimported, and it threw fewer errors and let me advance, and so I thought I was good to go.

  • Aspire, which was an awesome software. It allowed for easy vector manipulation, including joining all the dxf vectors that were supposed to make contiguous shapes, and putting dog-bone corners on all the slots.

Toolpath (in Aspire)

CNC

On the CNC machine, we noticed each line segment was treated separately, so Nathan said that was because when I imported the sketches from Fusion to Aspire, I didn't join the segments (honestly, I don't remember I miss any steps, I just followed the tutorial) It took a bit longer, but it turns out okay.

Assemble

In hindsight, those round edges are a bit "outer" than those straight lines, and those horizontal pieces have wider slots than my design, so maybe that's also because of the join issue.
