Rotation parts by means changing coordinates into input file
Rotation parts by means changing coordinates into input file
(OP)
Hi everybody,
I'm making a model that consists of three parts, two solids and one shell. I created the parts and then the assembly by using .cae interface but without move o rotate parts, in order to avoid relative coordinates in the input file.
For this reason I continued to edit my model by means the input file but a problem comes when I manipulate the coordinates of the nodes. If I exchange y column coordinates with z column of a solid part, in order to rotate the body, and If I import this in .cae interface to check contingent errors this part becomes translucent and you know that translucent body means that there is some mistakes.
I 'd like to know what I'm doing wrong in these steps, because if I do the same with a shell body no problems occurs.
Thank you for your time
Jack

RE: Rotation parts by means changing coordinates into input file
Why are you doing such strange things? Rotating a part can be done in the assembly module.
If you don't want part coordinates of nodes in your input file, you can write it out flat (= without part- and assembly structure). So the nodal coordinates are the same as the location in the assembly module.
RE: Rotation parts by means changing coordinates into input file
You would need to multiply the full set of nodal co-ordinates for the part with the rotation matrix for 180 degrees,
-1 0 0
0 1 0
0 0 1
Besides that why not do it in CAE as Mustaine3 suggested?

Dr Bwts your reply is clear but I don't know how can I write in out flat as Mustaine3 suggested me.
Could you please explain me!

RE: Rotation parts by means changing coordinates into input file
Anyway thank you very much for your suggestions, my problem is solved by using rotation matrix.
