Building Walls

Start the program. Change the view window to the quadview mode by clicking the quadview button. The mentioned button, as well as many other useful view navigation and control tools are grouped into the vertical view control bar at the right side of the view window.

Click the top left quadrant of the view (labeled as 'Top) to activate it. Then click the Quadview button again to maximize the selected top view. Alternatively, you can press Alt key down and double click the selected view quadrant to maximize it.

The view control bar is located at the right side of the view window. The Quadview button is highlighted and shows the tool tip.

Use the navigation controls to zoom out and move the view camera far enough from the origin, so that you will see enough space for modeling a complete building. Note that the status window displays changed camera parameters while you use the navigation controls. The view window should display about at least 15 meters wide area of space, and the camera should be moved at least 10 meters away from the origin. Undesired clipping problems arise, if parts of the building reach out all the way behind the camera.

[Note] Note

In this software, the XZ plane is the ground plane and Y axis points upwards. You can see the orientation of world from the coordinate system drawn in the view window. The direction convention can be changed using the Space selector of the File/Preferences window.

Activate the Building tool. It is located in the Creation tab of the toolbar.

First you need to draw a continuous loop, which defines the outer walls of the house. Click somewhere on the top left corner of the view window to start drawing the walls.

[Note] Note

Click the left button - do not drag the mouse while holding the left button down. Dragging operation is reserved for point snapping.

Move the mouse to see a rectangular shape drawn on the view window. By default, the building tool is in automatic mode, which draws a frequently needed rectangular base for the building. However, if the second click is exactly in a vertical or horizontal line from the first click, the tool continues accepting an arbitrary sequence of wall segments. Let's use the latter alternative.

Draw a line sequence, which defines the walls

Move the mouse to the opposite side of the view window horizontally. To easily find an exact horizontal level, just hold the Shift key down. When the first wall segment is 14 meters wide, click second time. Then continue drawing the base of the house until you have an L shaped form shown in the example picture. To finish the drawing, either click the Accept button in the toolbar or click again on top of the first wall point to close the loop.

[Note] Note

If you accidentally enter a point in a wrong position, hit the backspace key to step back in drawing.

A new object called 'buildingX' appears into the select window, which is located at the left side of the screen. The select window shows you the structure of your current scene. It is very important tool and we will learn more about it later.

Let's draw some inner walls next. While a building object is selected, the second row of the toolbar automatically shows you some frequently needed controls and tools, which are useful for building construction. Click the Sub Wall tool.

Sub Wall

Click two times to draw a horizontal wall as shown in the picture Note that you do not have to aim carefully to match the inner wall with outer walls. After activating the Sub Wall tool, take a look at the second row of the toolbar; it now shows the options of the Sub Wall tool. Snap Start and Snap End options are active by default, indicating that the tool will automatically fill the gaps. Finish wall drawing by clicking Accept or hitting the Enter key.

Draw the first sub wall with 2 mouse clicks. Length does not matter.

Activate the Sub Wall tool again and draw a second set of inner walls as shown in the picture. As you can see, sub walls can have multiple points and turns.

The second sub wall has 3 points
Save the project at regular intervals

It's time to save the work. Select the pull down menu File/Save As. After the save window has opened, define a suitable file name for saving, such as 'house'. You can also fill in some information to the Thumbnail fields. By clicking the thumbnail image, you can record the contents of the view into the thumbnail. Click OK to save the project.
