So I asked Gael if (hopefully) he still had the parts BEFORE the boolean operation.
But unfortunately he didn't...

It meant I had to clean up the mesh before to perform a new boolean.
So here is how I did it...

This tutorial assume that you have a minimum knowledge of the SketchUp tools.
Because it's mainly a "graphic tutorial" with a minimum of text.
At least you should now how to select things with a rectangle either going from right-to-left or left-to-right and by triple-click.

This tutorial makes use of 2 plugins : STL import/export (by Jim Foltz) and Curviloft (by Fredo6)

First I import the STL in SU.
You will need Jim Foltz's STL importer to do that.
I prefer to work in meters with SketchUp because it has been designed to deal better with big scale meshes. It was initially intended for architecture modeling. So you might want to import the part in "meters" unit.

InMoov's part imported in SU

As you can see there's a lot of "spikes" that have been generated by the boolean operation in Blender.
So the idea is to completely reconstruct the top surface without the letters and to do a complete new boolean operation later.

1 - Select all, Make group
Tutorial

2 - Rotate 90°
Tutorial

3 - Smooth edges (20° - can you see all the artifacts left by Blender's boolean ?)
Tutorial

4 - Edit group, Select, Cut
Tutorial

5 - Close group, Paste in place
Tutorial

6 - Make group
Tutorial

7 - Hide
Tutorial

8 - Edit group, Select, Delete
Tutorial

9 - Select (spikes), Delete
Tutorial

10 - Select, Delete
Tutorial

You might want to perform an extra step not shown here before going further (scroll down to the end of the tutorial)

11 - Skin (plugin Curviloft)
Tutorial

12 - Select boundaries, Validate
Tutorial

13 - Close group, Unhide all
Tutorial

You might want to stop here if you don't want any text on your parts. Or you might also continue with your own text...

EDITED : TIG has finished a release 1.1 of the plugin I needed so it's now possible to apply it at this stage.
Thank's TIG !

That's it !
The part is now clean and smooth.

Tutorial

The remeshed version of

  • InMRightV1
  • InMLeftV1

are available in my InMoov download section.

They are not exacly the same one as what can be obtained by following the tutorial because I have made them with a slightly different method.

Before step 11 I have divided all the boundary edges and made sure to have an equal number of segments (edges) on all sides. Then the triangulation made by Curviloft is even better !
So the parts available for download are better subdivided and have a better triangles distribution.

In a previous version of that tutorial I wanted to not use the plugin "Curviloft" to show you how to do step 11 by hand.
And then I wanted to subdivide the "hand-made" triangles. But none of the "Subdivide" plugins available could do what I was searching for...
So I had a discussion about that with Frenchy Pilou, and Pilou succeeded in convincing TIG to develop such a plugin.
The plugin TIG is working on is here.

I hope you liked that tutorial...
