MeshWrapper Tool
The MeshWrapper tools by Cadman provide a suite of tools for creating an outer shell around 3D geometry, simplifying the model and resulting in an evenly distributed surface mesh around the object.

The MeshWrapper Tools 
Watch the videos to gain a working understanding of the tools.

The Wrap Objects tool puts a uniform grid mesh around an object(s). The different grid projections are each a group within an overall MeshWrapper group. Each grid mesh is composed of a quad faces, and is compatible with quad face tools.

Select the object(s) to be wrapped with a mesh. Then fill out the Gridding Options dialog:

the Grid spacing size. If this number is a negative number, the longest dimension of the object(s) will be subdivided by that number to set the grid size.

the mesh projection style, either all around (surround), Top and Bottom, Front and Back, or Right and Left. 

the Shard filter specifies a grid edge multiplier. When an edge’s length exceeds this multiplier, its triangle will be left out of the final mesh. 

Stitch edges: The subgroups of the mesh are separate from one another, but their perimeter grid cells can be adjusted to match each other when the Stitch edges variable is set to ‘yes’.

 

The Seam Zipper tool stitches together the edges of two grid seams, or fills in a 1x grid within a mesh.
Make sure there is an edge on each end of the seam opening to make each end of the seam a single grid width 'boxed end'. A boxed end is when an edge has faces completely surrounding it on one side.

Select the ‘box ends’ of the seam and the Seam zipper tool stitches together the grid seams. 

The Reverse group faces tool reverses all faces within a selected group.
If a seam from Seam Zipper is facing inside out, reverse it with the ‘Reverse group faces’ tool. You can then explode the seam group and it merges into the surrounding mesh.

The Diagonals to quads tool turns pairs of triangles into a quad face (four sided face). Select the common edge between the triangles, (or multiple diagonals) and the tool will turn them into quad faces.

 

Go to Extensions > Cadman > MeshWrapper > Establish center line.

Establish center line takes points anywhere in 3D space and finds the circumcenter between those three points. Click two points, then the third point determines the center of the circle that passes through all three points. 

Go to Extensions > Cadman > MeshWrapper > Align profile.

Align profile orients the face normal (perpendicular) to the end of the line. The Align Profile tool wants you to select a profile face or group and a starting edge. The profile can face any way you want, it does not have to be flat to the ground. To put a profile on the end of a path, select the profile and the end-line of the path.

this one seems a little complicated to learn so before i give it the old college try let me ask, will this solve my problem? my problem is with painting surfaces or multiple quads with materials other than solid colors or official textures. For example on a van or car model. ive been trying to paint images on some models(like on hoods, doors, deck lids etc to simulate simulate airbrushing or replicate buisiness logos) but the image always looks like a picture behind broken glass , an effect ive come to call "kaleidoscoping". Ive been pointed in the direction of weight mapping apps but dont think i understand what weight mapping is. so will this extension solve my kaleidoscoping issues.

You need to edit INSIDE of the group or component so that you can select faces or the smooth surface. Then use a Projected Texture onto the faces and you won't get the kaleidoscoping (congratulations on the spelling).

Any texture can be made into a projected texture, just paint it onto a single face, right click on it and select Texture > Projected. Then sample that texture to paint on your surfaces.

tnks man verry useful looking for it for a lot of time !

Works perfectly with SU2016Pro. Triangulated a point cloud, which made the geometry into utter garbage. MeshWrapper drapes right on top.

Has trouble with smaller grid sizes on large format areas, but that's probably a limitation of SketchUp too.

Thank you for making the plugin free, but would pay for a license if you were so inclined to make a pro version.

This tool seems to be awesome if you can work with it! It would be nice to have a step by step tutorial on how to use it. The video describes what it can do, but for someone new to Sketchup it makes no sense since I don't know all the terminology used. Please create some point by point tutorials that will explain what everything means. Thanks

Terrible piece of code. Crashes SU 2016 Pro when trying to wrap mesh around a selection, even something less than 10mm in size.

Thought the full model was too much to wrap, so tried this simple little one and it hangs and have to end task. No other issues with SU or extensions, only this extension.

I was hoping to use this to wrap objects before 3D printing, since manually stitching all the edges gets really old fast.

Unfortunately, it does not work in sketchup 2016 Pro

I'm just trying this out today! It was very nice to meet you at Basecamp. Thank you for making this.
