Tip: Changing the Bend Radius of a Pipeline
You can have multiple entries for the same pipe size in the bend file, that is, a single pipe size can have multiple bend radius values associated with it, as shown in the following example of a bend file.

After you create a pipeline using a pipe size that has multiple bend radius values associated with it, you can set the bend radius value for that routing session by doing the following.
1. In a routing session, click Environment. The Piping Environment dialog box opens.
2. Select the required bend radius value from the Bend Radius list as the current one for that routing session. If you do not select a bend radius value, then the first value displayed in the list is set as the default bend radius value.
The bend radius value you set as current is valid only for the routing session. For a new routing session, the first value in the list is set as the default value if you do not set a different value.
You can change the bend radius value of a selected corner in a pipeline using the Modify Pipeline dialog box. Under Modify Options, select Corner Type. The default value displayed in the Bend Radii list is the current bend radius value for the selected bend. You can select a new value from the list.
 
* A routing session starts when you click Route Pipe and ends when you click it again.
