Part 2: Configurations & Modular Design

Following on our discussion in Part 1, I used a Gear Assembly to show the creation of size configurations for the Gear. In Fig. 1 below, you can see in the Configurations Tab that there are currently two configurations: the Default, and Medium. (I’m using screen shots because some of the feedback I received expressed concerns that the video went too quickly.)

In Fig. 2, I am creating a third configuration, Large. Note at the bottom there are two check boxes, the first of which Suppress Features, is very important. It provides a setting so that any features I create for this configuration are automatically suppressed in the other configurations, instead of me having to do it manually. You can also designate acolor for each configuration, which makes it simpler to recognize different configurations at the assembly level, which is particularly handy when the difference(s) between configurations is not immediately obvious. This applies at the part & assembly or subassembly level.

Fig. 3, the sketch for the primary extrusion of the wheel disk is open, showing me modifying the diameter dimension. You will note that on the dimension dialog, there is a tab selected, opening a flyout allowing me to specify which configuration this diameter is to apply to.
