Do you want to draw a simple garage with a flat roof or pent roof in cadvilla? In this tutorial, we show you step by step how to set the external walls, insert a garage door, and construct the roof. You will also learn how to add practical details such as a window and a wall cutout for ventilation. With the help of guidelines and the right settings, you will succeed with your planning in no time. Start your garage project now.

1. Create a guideline grid and define the rough height

[00:54] Set basic cross from guidelines

• In the first step, open a new 2D view via New.
• Deactivate the grid and the line width to be able to snap and orient yourself better.

• In the upper menu, go to 2D & Layout > 2D guidelines > guideline.
• First select Vertical guideline and place it. Then set a Horizontal guideline to create a basic cross.

[01:25] Parallel guidelines for the garage dimensions

• Use the shortcut P (Numeric parallel guideline) to determine the external dimensions of the garage.
• Set further lines at the desired distances in this way (in the video, e.g., 2.95 m, 3.20 m, and 5.95 m).

[02:19] Adjust rough height

• In the project tree on the right side, right-click on the Ground floor and select Properties.
• Set the Rough height to 2.45 m.
• It is mandatory to deactivate the Create automatic ceiling option and confirm with OK.

2. Draw external walls and insert garage door

[02:59] Draw walls

• In the menu, select Building > Walls > External wall > Between two points chain.
• Set the wall thickness in advance to 0.10 m (right-click in 2D view > Properties).
• Draw the walls along the intersections of your guideline grid.
• Tip: Use the key combination Ctrl + W to change the reference point of the wall (inside, center, outside) while drawing. End the input with Esc.

[04:55] Place garage door

• Select Building > Door > Door > Free positioning.
• Open the Properties with a right-click and select a suitable garage door under Selection (e.g., Garage 1_250x215).
• To place the door exactly in the middle of the wall, press the shortcut M (Centre point) and click on the two inner corner points of the front wall.

[06:22] Adjust the display of the door

• Select the placed door, press the right mouse button, and open the Properties again.
• Under Top view, change the Display type to Wire frame to hide the opening angle. Also set the Depth of the opening to 0.00 m.

3. Optional: Flat roof (ceiling slab) and supports

[07:31] Enter flat roof via ceiling slab

• Use the shortcut P to set further guidelines for the covered forecourt of the garage.
• Select Building > Ceiling > Ceiling >Insert with rectangle and drag the slab over the desired corner points.
• Press the Icon Ceiling on/off to activate the view of the ceiling.

• Select the ceiling slab in the 3D view, open the Properties via the right mouse button and adjust the Level (e.g., 2.35 m) as well as the Height (0.10 m).

[09:27] Place supports for the flat roof

• Select Building > Supports > Rectangular support > Free positioning.
• Set Width and Depth to 0.15 m.
• Place the supports at the front corners of the flat roof. Here too, use Ctrl + W for the appropriate insertion point.

4. Define and texture pent roof / sloping roof

[11:41] Preparation for the pent roof

• If you decide against the flat roof, select the previously created ceiling slab in the 3D view and delete it with the Delete key.

[11:55] Insert roof shape

• Switch to the 2D view and select Building > Roof construction > Insert roof > Insert rectangular roof.
• Drag the roof diagonally over the outer edges of the garage walls. The properties dialog will now open automatically.

[12:21] Set roof properties (pent roof)

• For roof sides 1, 2, and 4, change the Profile to Gable and set the Overhang to 0.10 m. Confirm inputs with the Tab key.
• For roof side 3, set the Profile to Hipped roof, the Pitch to 3.00 degrees, and the Height to 2.15 m.
• Deactivate all checkboxes under the Wood construction point, as we only need a solid roof slab.
• Under Cladding, set the Cladding thickness to 0.10 m and confirm with OK.
• Select the support with a right-click > Properties and change the height of the support so that it connects to the pent roof.

[16:29] Texture roof

• Activate a 3D view.
• Use the 3D functions > Transfer material function to assign the roof a concrete look from the catalog, for example.

5. Insert window and wall cutout (ventilation)

[17:26] Insert window construction

• Select Building > Window > Window construction > Free positioning.
• Press the right mouse button in the 2D view and in the Properties, set the opening dimensions Width and Height to 0.50 m and the Sill height to 1.50 m.
• Under Top view, deactivate the Show prompt height text option.
• Place the window in the wall. Use Ctrl + W and use from the constructural support the Point with distance from function (shortcut A)to align it exactly.

[19:52] Define wall cutout (external ventilation)

• In the 2D view, select the wall in which the external ventilation should be created. Pay attention to the selected wall side (is displayed in red).
• Press the right mouse button and select Create wall section.
• Select Building > Cutout > Wall Cutout > Rectangle.
• Draw the cutout freely in the 2D section view by clicking two diagonal points.
• Confirm the input with Esc. The ventilation is now visible in the 3D view.
