Working with Objects

Building Blocks

The Building Block is an object type that looks very similar to blocks from the Shapes section of the object library. Nevertheless, there are two major differences. Unlike library objects, you should draw a Building Block on the floor plan in order to create it. You can also use the Tile Transform tools with Building Blocks which is not possible with most of the library objects.

The functionality described in this section is only available in the Pro edition.

To add a rectangular Building Block, draw it on the floor plan using the Block Rect tool. Click and hold down the mouse button to start drawing a rectangle. You should then move the cursor to a new position and release the button.

To add a polygonal Building Block, activate the Block Poly tool. Click several times on the floor plan to add corners. Double click in order to specify the position of the last corner of the polygon and deactivate the tool.

Building Blocks can be used when you want to create a balcony floor, square column, horizontal beam, or a few steps.

Operations common for all object types are discussed in the Basics section. This includes:

The Properties of Objects in 2D section explains how to apply a stroke, fill or pattern to an object using the 2D Properties tab of the Inspector. There is also an option to choose different types of the 2D Representation.

The Applying Materials section explains how to apply materials to objects.

If you merge a Building Block with another object, the created object will have the Furniture type, the same as objects from the Shapes category of the library. You can use this technique when you need to adjust the size and location of a texture on the surface of a shape.

The "object" term is used to call Building Blocks in this part of the documentation.

Properties of Building Blocks in the Inspector

Most of the object parameters are located in the Inspector where you can change the geometric properties, or set up how the object looks on the floor plan or in the 3D view.

Building Block Parameters

Geometric Properties

The geometric properties of an object can be found in the Object Properties tab of the Inspector.

To resize an object, make sure that its dimensions are unlocked in the Inspector. You should then enter new values. To resize the object proportionally, select the Maintain Aspect Ratio option.

To resize an object on the floor plan directly, drag one of the handles on the object's selection frame. The handles are not displayed when the object dimensions are locked.

To rotate an object, use the Rotate tool in the Inspector or the rotation handle of the object's selection frame on the floor plan.

The Flip tools let you flip an object horizontally or vertically. The third button rotates the object by 180 degrees.

The Elevation parameter defines how high an object is placed in relation to the default floor level. Since the floor can also be elevated, the object's elevation is calculated from the floor with zero elevation. In a multi-story building, the elevation of objects on each story is calculated from the level of the respective floor.

To move an object vertically in the 3D view, press Cmd-Alt and drag the object with the mouse.

The Elevation parameter can be locked or unlocked. Locking is useful when you need to move an object horizontally in the 3D view.

Object Location in Relation to the Walls, Floor and Ceiling

The location of most of the objects in the room is pre-determined by their purpose. For example, tables and chairs can be anywhere in the room but must be on the floor. Wardrobes and bookcases stay on the floor near a wall. Most lamps hang from the ceiling or are affixed to a wall.

The program takes this object characteristic into account. When you add a lamp from the standard library, it automatically sticks to the ceiling or wall. Wardrobes are pre-programmed to snap the back side to a wall.

The Glue By set of options in the Inspector lets you select up to three object sides that will stick to the floor, ceiling or wall. The left, right, front and back sides can glue to walls. The top side can stick to the ceiling, and the bottom side sticks to the floor.

When the Glue By option is activated, the program may rotate an object, if this is necessary to place it in parallel to the wall.

Casting Shadows

You can turn the object's shadow on or off using the Cast Shadows option. Switching off the shadow can be useful for increasing the program performance when it renders the 3D scene. Some objects, such as area rugs, can cast shadow, but the latter will not be visible because the rug is on the floor. Deactivating the Cast Shadows option of such an object will make no difference to the 3D scene but can improve the rendering speed.

Changing the Shape of a Building Block

To modify the shape of a Building Block, right-click on it and choose Edit Contour Geometry from the context menu. The resize handles will disappear indicating the contour editing mode. The program will display the object's outline with diamond-shaped handles at corners called "contour points". To change the shape of the outline, you can move contour points.

To add a new contour point, right-click on the contour and choose Add Contour Point. To remove a contour point, right-click on it and select Remove Contour Point.

In the contour editing mode, the program also displays round handles in the middle of each side of the shape. If you move a round handle in one or another direction, the corresponding side will bend inside or outside of the shape creating an arc. While you are changing the curvature of a side, a number near the cursor changes from 0 (straight line) to 180 (semicircle). One of possible ways to create a circle is to draw a square and bend each side up to 90 degrees. Hold down the Shift key to snap to 15 degree steps.

Edited shape

Rounded sides of the object can be displayed in the 3D view as a number of facets or as a smooth surface. To make curvatures more or less smooth, use the Smoothness slider in the Inspector. Higher values may require higher computer performance while the 3D model is rendered. In the picture below, the two identical objects have minimum (at the bottom) and maximum (at the top) level of Smoothness.

Edited shape

When the Edit Geometry option in the Inspector is unlocked, you can activate the editing mode by double-clicking on the object.
