You will see that some of the elements that are valid for the “Slide” command are highlighted and other are de-highlighted. Among the highlighted elements make sure that the check box of the “Cline segs” is checked, recall from the previous tutorial that it is crucial otherwise the software will be unable to select the Cline segment to slide it. It is recommended to go through my previous tutorial to learn about “Find” and “Options” window.

Now drag the cursor on the Cline segment, click to select it and then drag it to slide it. The Clines before and after adjusting them are as shown in the following image:

As with more number bents can be dangerous for high speed signals thus application of the “Slide” command is inevitable and important to learn from beginning. Another important thing to learn is the minimum corner size. Activate the “Slide” command and open the “Options” window as shown in the following image.

In the above image notice that the minimum corner size is selected to be 20 it means that the corners of the Clines will not decrease beyond 20. That is when you slide the Cline segments so that the corner size is reducing then the Cline will stop to slide further when the corner size of the 20 is achieved, different corner sizes can be selected by enter the minimum corner size in the “Options” window as shown in the following image.
