Cannot change the CAD parameters (e.g., link length) #6

I want to change the CAD parameters of Model O.
I read https://www.eng.yale.edu/grablab/openhand/OpenHand%20CAD%20Guide.pdf and changed a parameter value in the Design Table, but it was not reflected.

What I did

  1. Download and extract https://github.com/grablab/openhand-hardware/archive/refs/heads/master.zip
  2. With SOLIDWORKS2022, open downloaded one of https://github.com/grablab/openhand-hardware/blob/8ae3f2155dde6066edb39cbd29b1b716d7b0f7df/model%20o/RX28-MX28/hand_o.SLDASM
  3. Open https://github.com/grablab/openhand-hardware/blob/8ae3f2155dde6066edb39cbd29b1b716d7b0f7df/fingers/t_pp_A.SLDPRT
  4. Open https://github.com/grablab/openhand-hardware/blob/8ae3f2155dde6066edb39cbd29b1b716d7b0f7df/fingers/params_finger_t.SLDPRT
  5. Open the Design Table of params_finger_t.SLDPRT
  6. Change length ratio (Ld/Lp) to 1.0
  7. Close the Design Table
  8. Switch to the window of t_pp_A.SLDPRT

What I faced

  • Rebuilding of t_pp_A.SLDPRT failed with errors and the changed parameter was not reflected:
    unnamed
  • When I checked the Equations of t_pp_A.SLDPRT, I found many errors. I assume this is the cause, but I'm not sure how to fix them:
    unnamed
