CATIA V5 Tutorial: What is Blend Corner and How to use it

Many times we come across corners during modeling components. Fillets in such zones are always challenging and in some complex cases, filleting becomes a major time taking process. Blend Corner option in Fillet command of Part Design and GSD Workbench of CATIA V5 gives more control of the shape you desire.

We shall now illustrate how to use Blend Corner in Part Design workbench.

Consider a simple block (CATPart) as shown in image below. The part is modeled in Part Design workbench.

Click on Edge Fillet toolbar icon and then select one after the other, 3 edges of the corner for which you want to apply blended option.

Click on More button in the Edge Fillet Definition dialog box. You will now have more control in the resulting fillet. Click on “Blend corner(s)” button. Preview the fillet. Give a Setback distance value as you desire.
The Setback Distance determines the area of blending for the corner. The Default value is 10mm. You can directly double click the set back distance value on the 3D model and change it. The set back distance along each edge can have it’s own value. Change the values as you like depending upon the shape you need.

After finishing, click OK.
The effect of applying blended corner to a part can be see in the image below.
 
The same part, after an edge fillet, but without a blended corner is shown in the image below. You can see the difference in the normal edge fillet part and the part with the blended corner by comparing the two images.
