On the Offsets tab of the Spreading of grates dialog, define grate offset values.
Define grate offsets:
- Offset of boundary - used to increase/decrease a spreading area; each component of a region contour is shifted by the specified value. A positive value indicates shifting the contour toward the inside of the region (reduction of the region), while a negative value shifts the contour toward the outside of the region (increase of the region). An offset value is defined with respect to the initial contour of the region.
- Offset of origin point - enables shifting the origin point of the spreading (an offset value is defined with respect to the initial contour of the region). The point can be shifted:
o in the X direction - along the vector perpendicular to the direction vector of the grate spreading
o in the Y direction - along the direction vector of the grate spreading
A positive value indicates an offset compatible with the vector sense
- Offset of level - allows shifting the plane of spreading. A positive value indicates an offset upwards, whereas a negative value indicates an offset downwards.
Use the buttons at the bottom of the dialog:
- Apply - after you click this, the grate spreading defined in the dialog is generated on the screen without closing the dialog. This lets you check whether the spreading has been generated correctly in the defined region.
- OK - click this to generate the defined spreading of grates and close the dialog.
- Hide - after you click this, the dialog is no longer visible on the screen. To restore the dialog display on the screen, press Esc.
- Close - click this to close the dialog without generating the grate spreading.
