STEP 5:CREATE THE SWEEP SURFACE.

Sweep Surface: is a surface, generated by translating or rotating one or more contours(across contours) along one or two other contours (across contours).Appl ications: usedwhen the across section of the surface at any point is constant (when the

surface is generated from one across contour and alone along contour).Used also, when the across section at any section is not constant (when the surface isgenerated from two or more across contours and one or two along contours).

It is very important which contour you choose as contour. Chain first the across contourstating from the intersection between the two contours (also known as starting position).Chain the along contour starting from the same position as shown below.

MAIN MENU Create Surface Sweep [ Define the across contour ] Single Select the arc, on the left hand side Done [ Define the along contour ] Chain Partial Select Entity A, near the arc. Select Entity B, near the edge of the rectangle. Done Do it
