Calculate Angles (in LDCad)

[Jaco van der Molen]

Method to close a triangle in LDCad:

• Select one "end" pin, then the matching articulation pin, then the other articulation pin and finally the last "end" pin.
  
• Right click -> selection info -> display the information panel and triangle angles.
  
• Choose either the red or green lines configuration depending on your needs.
  
• Click on the box with matching outline color to copy values in clipboard.
  
• Now select first articulation pin (to define rotation center) and parts belonging to first triangle arm.
  
• Press Ctlr R to enter manual rotation, and paste clipboard in angle value. Eliminate the second value, as we are working with the first arm. Accept.
  
• Select second articulation pin (to define rotation center for the second arm) and parts belonging to second triangle arm.
  
• Press Ctlr R to enter manual rotation, and paste clipboard in angle value. Eliminate the first value, as we are working with the second arm. Accept.
  
• Get rid of extraneous "end" pin(s).
  

...done!

Thanks Philo for those steps.
My problem was only step one. I just go by much trial and error to find the right pins and select sequence.
The way you put it I understand! Thanks.

The rest I knew, but just forgot.
