Changing the Height of a Wall Segment

In this Task 

• The origin (0,0,0) point will be moved to the top of a wall segment.
• A roof will be drawn by identifying the corner vertices of the exterior walls.
• The extended ortho will be used to snap to projected vertices on walls to exclude.

Associated Tasks 

• Viewing the house plan from an isometric angle.
• Relocating the Origin.
• Using Relative Coordinates.

Before you Start 

• Vertex and Extended snaps are activated. The GEO Magnetic Point and Auxiliary Lines should also be activated.
• The drawing origin is seated on the upper left exterior wall vertex, at the top of the wall. An Isometric view is required for this.
• The Fixed Relative Origin should be activated in Options | Advanced Preferences.

Take Note 

• When using an architectural template, the Roof will automatically be drawn on the ‘Roof’ layer.
• The height of the small outer wall at the bottom of the plan has been reduced to 2000 to better illustrate the placement of the roof.

changing the height of a wall segment

The height of the small wall segment shown below will be adjusted to 2000. Select this wall segment, then set the height to 2000 in the Selection Info palette.

 

relocating the origin

Relocate Origin

Ribbon : Modes | Coordinates | Relocate Origin

Default : Modes | Coord System | Relocate Origin

Palette : Tools | Palettes | Panel Setup | Coord System | Relocate Origin

By relocating the origin in the editor, all subsequent measurements are calculated from this point when using Relative coordinates.

Right click in the editor and set the view to Isometric South East. Select Modes | Relocate Origin and place the origin on the vertex shown below.

Drawing the Roof

Ribbon : Architecture | Roof | Add Roof

Default Menu : Architecture | Roofs | Add Roof

Palette : Panels Setup | Architecture | Roof

This tool creates a roof by defining each vertex of the walls. Specific walls can be selected, using the Roof by Wall option.When using the Roof tool, the finished roof will be drawn at the base of the walls. To prevent this, a Z coordinate is input to draw the roof at an elevation

 

Right click onto the Roof tool shown above and set the roof thickness to 30, the slope to 30° and the overhang to 300. When these parameters are set, click OK, then left click onto the Roof tool.

Make sure the Vertex and Extended snaps are activated. The Magnetic and Auxiliary Lines should also be activated.

Start the roof from the indicated position above. Draw in a clockwise direction, snapping only to the vertex corners of the walls.

Use the Extended Ortho to project to the outer edge of the wall, the point shown below. In the illustrations below, the view has been set to World Plan for illustrative clarity.

See position relative to the entire drawing below

Continue adding the roof by selecting the outer vertex point of the walls until the last point and the first point are coincident.

Select Finish.

The result is shown below in Plan view. The walls, doors and windows are temporarily shaded out.
