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

Download and extract https://github.com/grablab/openhand-hardware/archive/refs/heads/master.zip
With SOLIDWORKS2022, open downloaded one of https://github.com/grablab/openhand-hardware/blob/8ae3f2155dde6066edb39cbd29b1b716d7b0f7df/model%20o/RX28-MX28/hand_o.SLDASM
- While opening, I had to specify my local path to https://github.com/grablab/openhand-hardware/blob/8ae3f2155dde6066edb39cbd29b1b716d7b0f7df/params_print.SLDPRT
Open https://github.com/grablab/openhand-hardware/blob/8ae3f2155dde6066edb39cbd29b1b716d7b0f7df/fingers/t_pp_A.SLDPRT
Open https://github.com/grablab/openhand-hardware/blob/8ae3f2155dde6066edb39cbd29b1b716d7b0f7df/fingers/params_finger_t.SLDPRT
Open the Design Table of params_finger_t.SLDPRT
Change length ratio (Ld/Lp) to 1.0
Close the Design Table
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:
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:

The text was updated successfully, but these errors were encountered:
