Tube bending using tube laser

I am trying to desing a frame using solidworks like the picture below. On the internet I have found some information about designing te part of the tube that has to be cut out using a tube laser. However I have no idea at all how to bend the tube in solidworks to evaluate the result before actually cutting the tube. I do have a tube laser in house so is isn´t that expensive to try it but i would like to visualize my desing before actually making it. Does anybody knows were to find more information about desining something like this in sw ??
