Below, spatial modelling using AutoCAD.
AutoCAD 2006 in 3D. I used its 3D function to analyse a steel roof truss. It gets much easier to model using AutoCAD for linear spatial structures and transferring them to you analysis program of your choice.
Remember: That modeling needs not to be near perfect, but every inch perfect…that is if it is to be transferred to an analysis software. Perfectness is when all lines intersect exactly on the joints, not near intersection but exact intersection. If there’s a difference of less than a centimeter, the analysis software will call them two un-joined joints.
Then analysis using AVWin98. Figure below shows, truss system doing the calculation of moments after doing the complex modelling stance done in AutoCAD and transfering it to AVwin98 threw the import dxf file method, and defining each member(tricky one) together with the loads they carry(more tricky)
Thus some serious work was done here.
The elements had been defined and loads put in. There is a new version to this software, simply do not remember the name....probably something close to AVANSE or something. Will find out later.
The results to be presented at a future date. Most likely to forget.

Steel building kitsoptions exist for both homes and businesses. You can purchase kits for extra storage, sheds, garages, and even metal houses. There are also a lot of commercial and industrial options. You can find kits for airplane hangars, extra storage, larger buildings, and even correctional
