## Object Editing

| : Select objects. The same functionality than the select tool in object mode, look at the objects paragraph. : Symmetry the (xy) plane. A symmetry is done around the plane define by the x and y axis and the barycenter handle (of the selected objects). : Symmetry the (yz) plane. A symmetry is done around the plane define by the y and z axis and the barycenter handle. : Symmetry the (xz) plane. A symmetry is done around the plane define by the x and z axis and the barycenter handle. : Simplify. Merges all coplanar faces, if the resulting face is convex and if the faces material are compatible. For example, the trinagular faces in the left picture bellow are merged into one twelve edges face of the right picture bellow. Before symplify : After symplify : : Triangulate the selected objects. All the faces are separetated into triangules. This function adds no vertex. : Rotate the selected objects of 45 degrees around the z axe. The selected objects are rotated of 45 degrees aound the axis define by the z direction and the barycenter handle. For example : the 2 objects : become . : Rotate the selected objects of 45 degrees around the x axe. Same as above for the x axis. : Rotate the selected objects of 45 degrees around the y axe. Same as above for the y axis. : Perturb. Moves each face a random amount along its normal. The maximum translation length is asked before proceeding. For example, the sphere is tranformed into . : Stick. Moves one object so that one of its faces is stick on on faces of an other object. Two objects have to be selected. For example : First, the user select the green face of the cube : . The, he/she select the green faces of the sphere : . The result is the center of the sphere selected face is placed on the center of the cube selected face : . : Smooth. Smoothes the selected objects. : Cut with a plane. This tool opens the plane selection tool. An example : Cutting the cylinder with the (xy) plane result in the object . : Miror. Builds an object that is composed of itself and a mirored part of itself. The original object is not deleted. This tool opens the miror tool. For example, the square base of the pyramid (following picture) is selected, by selecting three of its vertices (the green ones). The red vertex is automatiquely selected because it is in the miror plane. The result is the diamond of the following picture. The original pyramid has been deleted in this picture. : Deform. Deforms the selected object. Opens the deform tool. : Cut with a polygon. Not done yet. : Edit. If the object is build with part (for example, lathe, extrude, heightfield objects), ppModeler retruns in a mode such that the user can edit this parts.
