In the Torchmate CAD it is simply a matter of placing a single circle the size of the bolt hole you want on screen, add a set of guide lines, one vertical and one horizontal, select this circle and drag the center of the circle to this cross-hair. Use the array tool to define a number of 5 bolt holes, a radius, and then click ok. Simply repeat the process with another rotation of 6 bolt holes and a different radius. Draw a large radius circle, of the OD on the bracket you want, and then drag and drop the center onto the crosshair. Once the patterns are placed, simply remove the center bolt hole and you have your part.
