Calculate Angles (in LDCad) - Jaco van der Molen - 2017-05-12
Hi all, Is there a way to exactly calculate the angles the 1x5 beam and 1x10 brick make? I kind of know how to do this in LDCad, but with these I don't know how. I have done this by hand and eye, but I'd like it to be exact. [attachment=2771] Thanks! RE: Calculate Angles (in LDCad) - Jaco van der Molen - 2017-05-12
Never mind, I got it. Suddenly remembered how to show info and work from 90 degree angles with a "helper" pin. [attachment=2772] The only thing that I do not fully understand is the sequence to select the pins. Selecting like I did I found the angles of the red triangle to be the ones I needed :-) RE: Calculate Angles (in LDCad) - Philippe Hurbain - 2017-05-12
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).
