Why are there missing surfaces or holes in my imported model?

With the release of Skimp 2.0, the chance of missing surfaces when importing a model has been greatly reduced compared to previous versions. 

However, the following information is provided in the rare event that an imported model has missing surfaces.

Models made on a small scale

Missing planes can occur when importing a model that was originally created on a very small scale.

For example, some OBJ files have vertex data that looks like this:

v -3.4101800e-003 1.3031957e-001 2.1754370e-002

v -8.1719160e-002 1.5250145e-001 2.9656090e-002

v -3.0543480e-002 1.2477885e-001.0983400e-003

Vertices with coordinates containing very small numbers are a problem, because SketchUp has built-in constraints that will not allow a face to be created if it is extremely small. 

If you import such a model, you might get a result that looks like this:

To solve this problem, you can try importing the model with 'meters' as the unit . This will greatly reduce the chance of missing faces.
If that doesn't work, you should open the model with another application (like Blender or 3ds Max) and resize the model. If you then resave the model as OBJ or FBX, Skimp should now be able to import it without any gaps.

Merge coplanar planes

In rare cases, when merging coplanar faces, some faces may be accidentally deleted. If this is a problem in one of your models, we recommend disabling the 'Merge Coplanar Faces' setting in Skimp.
