Reflecting Geometry to Another Floor

With this function, you can reflect the 2D geometry of an object to another floor. For example, a chimney added on the first floor layout of a building runs through the upper floors in the 3D model of the building. You can reflect the 2D geometry of the chimney to the upper floors, after which it will be visible in the floor plan drawings, which are later created from the floors. You can reflect the geometry to one or more floors.

When you move or delete the original object, the reflected geometry is also moved or deleted. Equally, when you move the reflected geometry, the original object is also moved. When you delete the reflected geometry, the original object is not deleted.

If you change the size of the original object, for example stretch or shorten a wall, the size of the reflection does not change. Equally, when you change the size of the reflection, the original object remains unchanged.

1. Select Modeling | Tools Reflect Object.
2. Select whether to draw the reflected geometry with the reflection color or with the true color:
   • Use reflection color - the function is selected in the auxiliary menu by default. When the function is selected, the reflected geometry is drawn with the blue reflection color.
   • Use reflection color - If necessary, disable the function to draw the reflected geometry with the true color of the building component.
3. Select the object, the geometry of which will be reflected. You can select several objects with the Ctrl key pressed down, or by using the area selection.
4. Select Confirm.
5. Select the floor on which you want to reflect the geometry. Select several floors with the Ctrl key pressed down. You will be prompted: "Leave this drawing-model pair active?" The question refers to the drawing-model pair to which you are reflecting the geometry.
6. Do either of the following:
   • If you want to work in the drawing-model pair on which you are reflecting the geometry, select Yes.
   • If you want to work in the drawing-model pair from where you selected the elements, select No.

In the example, the active drawing is the second floor layout of the building. The walls of the first floor appear as a reference drawing. The reflected geometry of the first floor chimney is drawn with blue color.
