DMU Sectioning  

The DMU Sectioning tab contains three categories of options:

• Section planes

• Section grid

• Results window

Section Planes

Default color

Use the color chooser to define the default color of section planes.

By default, color is as shown above.

Normal X, Y, Z

Select the option specifying the absolute axis along which you want to orient the normal vector of the section plane (master plane in the case of slices and boxes).

By default, the normal vector is oriented along X.

Origin

Select the option locating the center of the plane:

• 0,0,0: at absolute coordinates 0,0,0

• Selection: at the center of the bounding sphere around the products in the selection you defined.

By default, the origin option is set to Selection.

Hide the plane

Selecting this check box hides the plane on exiting the command. If cleared, the plane is kept in the Show space on exiting the command.

By default, this check box is selected.

Hide the section results in the No Show space

Selecting this check box transfers the section results to the No Show place on exiting the command.

By default, this check box is cleared.

Automatic computation of the result

Selecting this check box automatically updates sectioning results while manipulating the plane. If cleared, sectioning results are computed when you release the mouse button.

By default, this option is selected.

Wireframe elements cut

Selecting this check box takes wireframe elements into account and the section plane sections any wireframe elements present. Points represent the intersection of the plane with wireframe elements.
If cleared, wireframe elements are not taken into account.

Though this option is selected, sectioning will not have any results with infinite lines.

By default, this check box is selected.

Allow measures on a section created with a simple plane

Selecting this check box gives the same 3D section cut display for a plane as in the case of a slice or box and lets you make measures on the wireframe section cut.

By default, this check box is cleared.

Section Grid

Mode

Select the option to locate the grid:

• Absolute: sets grid coordinates with respect to the absolute axis system of the document.

• Relative: places the center of the grid on the center of the section plane (master plane in the case of slices and boxes).

By default, the mode is set to Absolute.

Style

Select the option defining how the grid is represented: Lines or Crosses.

By default, the style is set to Lines .

Steps - Automatic filtering

Selecting this check box automatically adjusts the level of detail of the grid display when you zoom in and out.

By default, this check box is cleared.

Steps - Width, Height

In the Width and Height boxes, type or select a new value to specify the spacing between grid lines. Units are current units set using  Tools  >  Options.

By default, width and height are set to 100.

Steps - Automatic grid resizing

Selecting this check box automatically resizes the grid to section results when moving the section plane. If cleared, the grid has the same dimensions as the section plane.

By default, this option is selected.

Automatic grid resizing ON:

Automatic grid resizing OFF:

Results Window

Automatically open

Selecting this check box always displays the Section viewer when in the Sectioning command.
Note: If cleared, the preview window is displayed.
If, in addition, you clear the Sectioning preview option in the Digital Mockup General tab (Tools > Options > Digital Mockup > General), then no viewers are displayed.

By default, this option is selected.

Window size (pixels)

This option is available only if you select Automatically open check box. Selecting this option button specifies the dimensions (size and positioning) for the Section viewer (i.e. the section results window).
This user defined option is persistent, i.e. once you arrange your section viewer, you always retrieve it as defined until you modify it again.
 

• Width: specifies the width value in pixels for the Section results window. Either type the value in the field or use the the drop-down list box  
• Height: specifies the height value in pixels for the Section results window. Either type the value in the field or use the the drop-down list box  

By default, this option is selected and the width and height values are set to 200 pixels.

Tile vertically

This option is available only if you select Automatically open check box.
Selecting this option button arranges the open sectioning viewers as non-overlapping tiles, top to bottom, left to right. Note that, the window size option button is disabled, i.e. the window size corresponds to the tile.

By default, this option is cleared.

Always 2D view

Selecting this check box locks the Section viewer in a 2D view. If cleared, you can work in a 3D view.

By default, this check box is selected.

Automatically reframe

Selecting this check box automatically fits the results into the available space in both the Section viewer and preview window when manipulating the section plane in the document window.

By default, this check box is cleared.

Section fill

Selecting this check box fills in the section to generate a surface for measurement and display purposes.

By default, this check box is selected.

Use curves instead of polylines for export

Selecting this check box allows you to export the sections in form of curves instead of polylines.

By default, this check box is cleared and the sections are exported in polylines.
