Rerun:Tip--Create a gently bowed shape

In this tip, you will learn to control an N-sided Surface to create a gently bowed shape in NX.

 

Step 1:  Create a sketch of a triangle with equal length lines and mid point constraints. 1 dimension of 100mm.

 

Step 2: Create the arcs with their centers on each straight line, tangencies, and equal length arcs.

Step 3: Use the fillet command with equal radius arcs and place the dimensions on the arcs as shown.

 

 

 

Step 4: Extrude a 10mm ribbon with the body type = sheet, and a 27 degree angle as shown.

 

 

Step 5: Blank out all the curves and create an “N-sided Surface” on top of the ribbon. Use the “Match Boundary Face” option.

 

 

 

Step 6: Extend the surface with “Trim and Extend”. Extend about 5 mm below the initial sketch plane.

 

Step 7: Once you have extended it you can trim it with the initial sketch plane and create a bounded plane on the bottom of it. Then sew it up into a solid.

And you're done!
