Surface Recapitulation Exercise
Load the part called surface_recap_begin.CATPart from the ''Companion'' and save the part in the Students directory.

1. First you are going to Offset 7 surfaces (1 mm.) from the inside of the Solid Clamp.

Double Click on the Offset icon.

In the Offset Surface Definition dialog box enter an Offset value of 1mm.

Select the first surface as shown.

Click on OK to confirm the Offset surface creation.

As you have double clicked on the icon, the Offset function is still active.Select the other six surfaces with the same method.

Once you have created the seven surfaces clcik on the cancel button to deactivate the function.

Click on the Blend icon  .
The Extremum Definition Dialog box is opened, select the Maximum option.
Select the edges and the support surfaces as shown below.



Click OK to confirm the blend creation.

3. You are going to Insert a JOIN operation to assemble all the Offset surfaces and the Blend surface into one single surface.

Multi select the seven Offsets and the created blend. 

Click on the Join icon  .

All the pre-selected objects are added to the join list. Click on OK to confirm the Join creation.

4. You are going to Extract a Boundary Curve from this JOIN surface.

Select the Boundary icon  .

Select an edge of the Join as shown below. 


Click on OK to confirm the Boundary curve creation.

5. You are going to Create a Sweep Surface using the circular section curve (Output1) per parameters on the right.

Click on the sweep icon  .

In the Swept Surface Definition dialog box choose a Line Profile type and ’’With reference surface’’ Subtype.

Select the Output1 circle as Guide curve1 and the Output1-Plane as Reference surface.

Key in –88 degrees as Angle value and 100mm as Length 1

Click on OK to confirm the Swept Surface creation.


6. You are going to create a Loft tangent to the Join and the Sweep surfaces
Select the Loft icon  .
Select the Output1 as first Section and the Sweep.1 as tangent surface.

Select the Boundary.1 as second section and the Join.1 as tangent surface. Check that the two profiles are in the same direction.

Click OK to confirm the loft creation.
