Example: Cast Part (2-D -> 3-D)

This example illustrates the conversion of the 2-D drawing shown below to the 3-D model of a cast part.

(1) front view, (2) side view, (3) top view

Proceed as follows:

Load the REKO_BSP4.SZN file and activate the conversion module (3-D Standard > New > Extruded > 2-D->3-D Conversion). The derivation of the 3-D model comprises three steps:

• Step 1: Define views
• Step 2: Select polylines
• Step 3: Take over holes and subtractions

Step 1: Define views

1. Select the Views function from the 2-D->3-D Conversion menu.
2. Create a selection box (1), (2) for the front view and specify the intersection point of the left edge and the upper edge as the reference point (3).

3. Create a selection box (4), (5) for the side view and specify the end point of the right edge as reference point (6).
4. Create a selection box (7), (8) for the top view and specify the start point of the upper edge as reference point (9).

Now select the required polylines.

Step 2: Select polylines

1. Select the Parts from View function from the 2-D->3-D Conversion menu.
2. Identify the polyline (1) in the front view.
3. Identify the polyline (2) in the side view.
4. Identify the polyline (3) in the top view.

Step 3: Take over holes and subtractions

1. Select the Holes function from the 2-D->3-D Conversion menu.
2. Identify the 3-D model (1), then select the hole contours (2) - (8) in the front view.
3. Right-click to end the hole contour selection. The holes will be created.

4. Select the Subtractions function from the 2-D->3-D Conversion menu.
5. Identify the 3-D model (9), then select the contour of the subtraction (10) in the front view.
6. Right-click to end the selection.
7. Identify the start edge (11) and the end edge (12) for the subtraction.
