To Create a Planar Cross Section Using the Default Coordinate System
1. Open a part or an assembly.
2. In Part mode, perform one of the following steps:
◦ On the
View tab, click the arrow next to
Default Csys. A gallery opens.
◦ On the Home tab,
1. Click the arrow next to Sections group.
2. Move the pointer over
Default Csys. A gallery opens.
In Assembly mode, on the
Home tab, click the arrow next to
Default Csys. A gallery opens.
3. To open the Section tool with reference set to one of the axes of the default coordinate system, click one of the following buttons.
a. X Direction — Sets the reference to the X axis.
b. 
Y Direction — Sets the reference to the Y axis.
c. 
Z Direction — Sets the reference to the Z axis.
An Options Toolbar opens and a cross section is automatically created using the corresponding plane of the coordinate system. For example, if you have selected Y Direction, then the cross section is created on the ZX plane.
A Line dragger appears at the origin of the coordinate system. The Line dragger is normal to the clipping plane and indicates the clipping direction.
You can expand the Options Toolbar to open the Floating Dashboard.
|  Creo Direct automatically creates a default coordinate system if the model does not have one. |
4. You can create a cross section choosing either Offset or Through as described in Step 4 and Step 5.
| The default dimension constraint type is Offset. You can change the default dimension constraint type to Through. See planar_xsec_default_type. |
To create a cross section at an offset from the selected reference, do the following:
a. Click and type a value for the offset distance or drag the handle in the graphics window.
b. To change the reference, on the Floating Dashboard, on the
Position panel, select an axis from the
list.
5. To create a cross section passing through the selected reference, do the following:
a. From the
list, select the constraint type
Through.
b. Select one of the following planes:
▪ XY—Places the cross section through the xy-plane defined through the x- and y-axes of the datum coordinate axis.
▪ YZ—Places the cross section through the yz-plane defined through the y- and z-axes of the datum coordinate axis. This is the default.
▪ ZX—Places the cross section through the zx-plane defined through the z- and x-axes of the datum coordinate axis.
6. In the
Direction panel, click
to change the clipping direction.
7. Change the location of the cross section by using the dragger or click
to enable free positioning of the clipping plane. When free positioning is enabled, you can translate and rotate the orientation of the clipping plane using the dragger.
8. Middle-click to complete the operation. The cross section is added to the Model Tree.
