The Rewrap Command (part 3)

We all know that the Rewrap command is useful for interpolating mesh data as well as smoothing noisy data. This post continues our look at the command with a third example. The first two examples can be found by visiting this post and this post.

Example #3

Generating a mesh for cross-sections: Generating cross-sections can be useful if you plan on creating lofts. Using 3d-sketch tools, you can smooth out and edit your cross-sections to create smoother loft surfaces.  Cross-sections can also be used to generate sweep paths, guide curves, and boundary-fit curves. What if your mesh is missing data? Or there are mesh features that you would like to omit from your final model? If each cross section was a 2d section we could use our sketch tools to fit geometry over the missing data. Or if they are 3d sketches, we manually could fill in the gaps with matched splines, and delete sections we don’t want. Of course, a much more elegant method would be to use the rewrap command.

In this example we have a Rapidform helmet. Most us application engineers in the company put these on to protect ourselves from the sales reps when the end of the fiscal year nears…

The scan itself is missing data and there a few features that we want to ignore during our modeling. With region groups, we can easily separate the areas of interests.

After deleting the unwanted data, or copying and pasting the regions of interest, we can run the rewrap command to simultaneously fill holes and defeature.

Now we can generate continuous cross-sections for Lofts…

for Boundary-Fit Surfaces…



or to help with Solid Modeling.
