Section 1.1: Geometry Creation

Step 1: Create the reference points

Create 3 points with the coordinates 0 0 0, 0 5 0, 5 0 0 with Explicit Locations, from the Create point tool in the geometry menu (Fig.1.2). To display the point, click on Fit-Window or “x” on the keyboard. If you want to display the point names like in Fig. 1.2 right click on points in the tree model menu and select Show Point Names.

Step 2: Create the bottom edge

From the Create/Modify Curve menu select the third option Create a Circle or arc from a center Point and 2 points on plane and select the points in the same order as they were created (Fig. 1.3).

Step 3: Create the bottom surface

From the Create/Modify Surface menu select the first option Simple Surface with the From 2-4 Curves Method and click on the curve previously created. The result is the surface shown in Fig. 1.4.

Step 4: Copy the geometry to create the top geometry

From the Transform Geometry menu select Transformation tool and select all the geometry done, activating the radio button Copy with Explicit Method using the coordinates 0, 0, 10, for x, y and z, respectively (Fig.1.5).

Step 5: Create the cylindrical surface

From the Create/Modify Surface use the same option of step 3 and select the two curves shown in Fig. 1.6. With this step the geometry is completed (Fig. 1.7).
