## Objects

| : Select objects. A left click on an object handle selects the object. The selected objects are drawn in yellow, the non-selected objects in blue. If the "Shift" key is pressed while clicking, the object is added to the selection list. A right click changes the current action to move selected objects. : Move selected objects. The selected object are moved by dragging the selection handle. Press "Enter" to enter numerical translation. A left click changes the current action to Select objects. : Rotate selected objects. The selected objects are rotated by dragging the action handle. Press "Enter" to enter numerical rotation. A left click switch to Select objects. : Scale selected objects. Press "Enter" to enter numerical scale factors. A left click change the current action to Select objects. : Duplicate selected objects. Look at the duplicate paragraph : Delete the selected Objects. : Change the material properties of the selected objects : Add a cube. The number of subdivision along each axes can be defined. The cube size 10x10x10. The following window allow to configure the subdivisions. The result is shown on the right. : Add a cylinder. The number of slices is aked in a window. The height is 10, the diameter is also 10.The following pictures show the result with 2 slices. : Add a sphere. Adds of sphere of diameter 10 at the origin. The number of longitude circles is defined by the current spline resolution (Options menu). The number of lattitude circles is half of this number. The following picture show the result with the default spline value, 12. : Add a 2d polygon. ppModeler enter in 2d polygon mode. The tool boxes now contians only one tool box (), and when the editing is finished, a 2d polygon is added, either one or two sided. The polygon is defined in the (xy) plane. : Enter in patch editing mode. No done yet. : Add a Skin object. : Add a pyramid. The base, on the (xy) plane, is defined by a 2d polygon. The height of the pyramid is 10. : Add a revolve object. The profile is define by an open 2d polygon. The revolve object can be of two types : like a torus, defined by a closed polygon. like a revolve object, defined by an open polygon and an axis. For example, the following pictures give the defined polygon and the resulting object. For a closed polygon : -> and for an open polygon : -> For a closed polygon, the object is build by rotating the polygon around the y axis, and the number of step is defined by the spline resolution. For an open polygon, the rotation is made arround the axe defined by the first and last point of the polygon. : Add a sweep object. An object is defined by moving a closed 2d polygon along a 3d curved. Let's look at an example : First, the user defined a contour : . Then, the extrude path : . The resulting object is : : Merge. Merges selected object into one. The name of the new object is aked. : Unmerge. Unmerges the selected ojects. Works only on merge objects, created with the merge tool.

Some other types of object can be reach via the Object menu :

- blob
- heighfield
- plant, defined by l-system
- 2d polygon draw on an image
- matematical surface defined by z = f(x, y)
