One of the tools in the Sheet Metal Command Manager that is unfortunately overlooked in the official Training Manuals is the 'Vent' command. It is relatively straight forward to use and therefore I have decided to write a short post about it. We can simply by creating a Sketch of our desired vent in conjunction with the command obtain some great features.
For this example I have produced a simple sketch offsetting Circles and creating 8 lines spaced 45 degrees apart.
In the Vent property manager we specify the following:
'Boundary' This would usually be all sketch segments required to form a closed boundary.
'Geometry' This is based upon a planar or non-planar face but the sketch must fit on the selection. We can also specify draft and whether we require filets at intersections.
'Ribs' Here we select the entities that will be our Ribs and the width required.
'Spars' We can add additional entities and in this particular example the diagonal lines have been used.
