(...) 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)

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)

(...) Hi Jaco, The right wing is being rendered weirdly because LPub thinks that the right wing is being added using a mirror matrix. You have wing1.ldr and wing2.ldr in your model. In theory you could get by with just wing.ldr, because wing2.ldr (...) (15 years ago, 14-Jun-09, to lugnet.cad)

Hello Michael Heidemann DatHeader 2.0.5 does not add CR/LF to the end of a file. This happen when you allow to program format comments (to '0 //' form ). I reference to File Format Restrictions for Official Parts (URL) El'dar Ismagilov (15 years ago, 14-Jun-09, to lugnet.cad)
