(...) You can also use SR 3D Builder to build your mirrored/symmetric models. You build a side and the program will build the other, mirrored one. It automatically substitute and rotate non symmetric parts and is compatible with lDraw/MLCad file (...) (15 years ago, 15-Jun-09, to lugnet.cad)

(...) Not sure if this helps but... If you solve (M11+1) x + M12 y = - M13 M21 x + (M22+1) y = - M23 and then normalise the vector (x,y,1) the result will be a vector normal to the mirroring plane. To test that you indeed have a rotation/mirror you (...) (15 years ago, 15-Jun-09, to lugnet.cad)

(...) Way back in olden times we created some programs to automate the mirroring process. (URL) anyone feel like testing the programs out to see how well they hold up with all the new parts available today? Don (15 years ago, 15-Jun-09, to lugnet.cad)

(...) I don't think so. (...) What if you mirror it again to get back to an unmirrored state, then run the code in mirwiz to create a submodel that only looks mirrored (but actually just flips pieces to look mirrored and substitutes opposite wedges, (...) (15 years ago, 15-Jun-09, to lugnet.cad)

Hi gang, If I have an LDraw Type 1 line that adds a submodel, and the rotation matrix of the line is a mirrored matrix about one and only one axis, can one calculate which axis the model is mirrored about? Can one do so if the user mirrored *and* (...) (15 years ago, 14-Jun-09, to lugnet.cad)

(...) Well, scratch that analysis. wing2.ldr and wing1.ldr are exactly the same model. When you added wing2.ldr you *did* use mirror matrix. LPub 4.0.0.2 notices that you used a mirrored matrix, and rendered the wing with the mirror matrix rotation. (...) (15 years ago, 14-Jun-09, to lugnet.cad)
