# CAD Software for Students: Learn Assembly Modeling Techniques with Solid Edge

Retired

Learn how to make design modifications at the assembly level using the power of synchronous technology. This saves you from having to go in and out of individual parts, which can be tedious and time consuming. Changes at the assembly level are much faster—not to mention easier—to make.

The example shown in this tutorial uses a servo motor. Using the Drag Component command, we can simulate the motion of the motor based on the assembly relationships between the parts. The scenario we will test today is how changing the location of a wire in the assembly will impact the motion of the jaws.  Now to do that, normally we would have to make changes at the part level, which would require us to go in and out of the wired part in order to make it longer and measure the distance between holes. The video tutorial below will show you how to do it very quickly and easily in synchronous technology.

The first thing we want to do is look at the assembly relationship to that wire. We see that there is a relationship here on the end, which is the one that we’re going to be replacing. Let’s go ahead and delete that relationship. What that’s going to do is allow the wire to move freely now, or rotate about the jaw. Make the modification using synchronous technology by relocating the steering wheel onto that end of the wire. Now let’s point the steering wheel to the other end. That gives us a starting point for the rotation so we can ensure that it lines up directly with the hole on the other end.

Now it is located correctly for the assembly relationship. Just like before, we can use the face relationships between parts, and in this case, we’re going to be using the concentric face relationship to make the wire concentric with the hole in the servo. It changes automatically, and we didn't have to measure a thing! All we have to do now is reestablish the assembly relationship between those parts. In this case, that means an axial alignment between the hole and the wire.

With the assembly relationship reestablished, we can again show the motion by dragging. The left jaw now opens just a little bit wider than it did initially, being located in that new position. It’s very powerful to be able to make these modifications at the assembly level. Makes assembly modeling much easier with synchronous technology.
