Wich would be the best way to sketch this frame in 3D? If i copy the sketchs they loose their configuration ( dimension, relations etc), I couldnt find any pattern for 3D sketchs.
There is no pattern functionality in 3dsketch. That beeing said, you don't need it because you only need to make one set of the cross pattern in the sketch. Then, after you make structural members to it, create a linear pattern of the weldment bodies.
But if you prefer sketches, then you can create a plane at each section and insert derived sketch of the cross pattern.
If you use different members for you cross bracing then patterning the bodies won't work. Insert a reference plate at the location of your bracing and then use derived-sketch or convert entities to copy the x-brace line. Be careful not to overload 3D sketches. They can become a hassle to edit and over-constrain errors are not uncommon. Better to use more 2D sketches.
