Working Plane Properties

View: VisibilityWorking PlaneWorking Plane Properties

In this dialog box you may specify the size and raster of the working plane. The visibility of this plane may be changed by choosing the Draw Working Plane option in the View: OptionsView Options &endash; General dialog.

The working plane is especially important for interactive shape generations where all coordinate input from the mouse pointer will be projected onto this drawing plane. You may not draw a shape which is outside the current working plane. However, during your shape construction the working plane size will be updated automatically to be large enough to enclose all your objects.

Please note that the working plane is only enlarged and does not shrink during the construction process. In order to fit the working plane best to the current model size you may choose View: VisibilityWorking PlaneFit Working Plane.

Size

Specify a valid expression for the working plane size. The working plane will extend by this amount in both transversal coordinate directions.

Raster frame

• Width: Specify a valid expression for the working plane raster. This raster is used only for displaying the drawing plane and has no effect on mouse input.

• Auto: This check button activates or deactivates the automatic raster width adjustment mode. When in auto mode, the raster size is automatically adjusted if the working plane is rather large according to the current raster size.

• Snap: This check button activates or deactivates the snap mode. When the snap mode is active, all mouse cursor locations in the drawing plane are mapped to the fixed Snap width raster.

• Snap width: Specify a valid expression for the raster snap width. This raster is not used for displaying the drawing plane but for mapping mouse pointer locations to a fixed raster. The default raster is 0.1 units. All mouse pointer locations which are projected onto the drawing plane during the interactive shape generation process are then mapped to the fixed snap raster

• Auto:  If the auto button for the snapping is enabled, on change of the raster size, the snap width is checked and if not within a valid range compared to the raster will be adjusted.

OK

Press this button to apply the specified working plane settings. The working plane will be updated immediately in the main plot window. The current Raster Width setting of the working plane will always be shown in the status bar when the working plane is visible.

Cancel

Closes this dialog box without performing any further action.
