ically respond to associated changes. It typically occurs
on the route sketch that relates to the assembly geom-
etry or when an auto region is converted to a paramet-
ric region.
You can switch between the driven dimension and the normal sketched
dimension using the Drive Dimension tool on the standard toolbar. Once a
driven dimension is switched to a normal sketched dimension, you can edit
the value. If converting the driven dimension to a driving dimension will
over-constrain the geometry, the conversion is not allowed.
Driven Dimension tool
In the route environment, normal sketched dimensions can be manually set
using the General Dimension or edits in place. If you want to place dimensions
based on geometry outside of the active route, you must first include it in the
route sketch using the Include Geometry tool.
General Dimension tool
NOTE Placing dimensions may over-constrain the route sketch. You may also fail
to switch the dimension type. You can identify the geometric constraints as needed.
In this exercise, you edit the segment length in place. For more information
about how to place and edit dimensions on the route sketch (3D sketch), refer
to Autodesk Inventor Tube & Pipe Help and Autodesk Inventor Help.
Edit the route dimension
1 Activate Route03 in the AirSystem1:1 run.
2 Double-click the dimension on the last segment as shown in the following
