Example: Flange (2D -> 3D)

This example illustrates the conversion of the two 2-D single part views shown below to a 3-D flange via rotation.

Front view and side view of a flange

Proceed as follows:

Load the REKO_BSP2.SZN file and activate the conversion module (3-D Standard > New > Extruded > 2-D->3-D Conversion).

The conversion of the 3-D model comprises three steps:

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

Step 1: Define views

Select the Views function from the 2-D->3-D Conversion menu.
Draw a selection box (1), (2) for the front view and specify the end point of the centre line as reference point.

Draw a selection box (3), (4) for the side view (left) and specify the centre point of the inner circle as reference point.
As a third view is neither available nor required, select ESC/END to end the view definition. The views are now defined.

Next, the required lines need to be selected.

Step 2: Derive 3-D model

Select theRevolved Solidsfunction from the 2-D->3-D Conversion menu.
Identify in the front view the polyline you want to rotate (1).
Determine the rotation axis (2).
Specify the start point of the centre line as the reference point for rotation.

HiCAD will automatically derive the 3-D model. If required, you need to go to another screen area in order to view the 3-D model (e.g. using the Screen key).

The first step towards the 3-D conversion has now been taken. Next, take over holes and threads.

Step 3: Take over holes and threads

Select the Holes function from the 2-D->3-D Conversion menu.
Identify the 3-D part (1).
Then identify all 2-D polylines for the hole contours (2) - (10).
Right-click to end the selection.

The 3-D model is now appropriately modified. If you want to rotate the model and see the result, select the Rotate View function from the upper toolbar.
If you want to shade the 3-D model, select the Shade 3-D View, with edges or without edges from the Views toolbar.
