Mr. Helio Bailly Guimaraes 0 Report post Posted August 16, 2013 Sometimes the angle on a determined local of a surface is an important parameter. Thus, I created a simple feature which draws an arrow (surface normal) at a determined position (du, dv) for visualization.Furthermore, it exports the angle of the normal referred to the global system (X, Y, Z) as (Xang, Yang and Zang). I used this feature on a project where I wanted to control the surface derivative at the aft part of my bulbous bow (see image attached) for example. The feature can be used within any kind of surface (just need to change the argument type on the feature edition).You can also visualize the normal arrow on the opposite direction of the normal of the surface, by simple clinking "invert". NOTE that the normal of the surface is still the same, only that the arrow is been draw in the opposite direction of the surface normal direction. Hope it can be useful for you too.
