2. A cone on a sloping plane

Although this is a very simple model, it demonstrates the steps commonly used to create models with Amapi 3D: 1. Build the construction lines, meshes or basic volumes. Here a cube will be the base for the sloping plane and a circle will be the base for the cone. 2. Model by modifying the construction shapes. Here we will cut the cube to make a sloping plane. 3. Assemble the parts to make the final scene. Here we will place the cone on the sloping plane.

The sloping plane

Þ Step 1: Make a cube

q Tool: Cube q Do it: We draw a cube. q See the detailed explanations in the chapter: User Manual/Tools/Construction/3D Primitives/Cube

Þ Step 2: Cut the cube

q Tool: Cut q Do it: 1. Take the Cut tool. 2. Click to indicate the origin of the action. 3. Click again to set the pivot point of the cutting angle. 4. Click to validate. The cut edge is open. q See the detailed explanations in the chapter: User Manual/Tools/Modeling/Cut

Þ Step 3: Create the sloping plane’s face

q Tool: Surface extract q Do it: Do a manual or automatic extraction of the face. q See the detailed explanations in the chapter: User Manual/Tools/Construction/Facet Extraction

The cone

Þ Step 1: Draw the circle

q Tool: Drawing Tool, Circle q Do it: Next to the sloping plane, draw a circle which will be the base of the cone. q See the detailed explanations in the chapter: User Manual/Tools/Drawing/Circle

Þ Step 2: Extrude the circle

q Tool: Extrusion q Do it: Extrude the circle up to the desired height for the cone. q See the detailed explanations in the chapter: User Manual/Tools/Construction/Extrusion/Direct Extrusion

Þ Step 3: Finish the cone

q Tool: Weld q Do it: Weld the top section of the cone. q See the detailed explanations in the chapter: User Manual/Tools/Assembly/Welding

Put the cone on the sloping plane

q Tool: Lay On q Open the model file: poser q Do it: 1. Select the Lay On tool (the cone is the current object). 2. Click the face under the cone. 3. Now, click on the sloping plane. 4. The geometric centers of the two faces are against each other. If necessary, you can cancel the operation (PC: CTRL+Z or Mac: Command+Z) and do it again with another face of the cube. q See the detailed explanations in the chapter: User Manual/Tools/Assembly/Lay On
