Specify method for the UV parametrization
- Projection
In this case for the UV parametrization of each facet the coordinates are projected on a certain plane
- Use current UV data
In this case it is used the texture coordinates which are already set. This method can be useful for the models which come from other programs, where the texture coordinates were set (on the picture below it is possible to see the example for the model from SketchUP).
Specify the projection direction for UV parametrization
This option is valid only for the Projection method.
- Automatic
In this case the direction of the projection is chosen automatically by the program.
- X - axis
In this case as a projection direction the X – axis of the current workplane is used.
- Y - axis
In this case as a projection direction the Y – axis of the current workplane is used.
- Z - axis
In this case as a projection direction the Z – axis of the current workplane is used.
Specify the parameters direction for UV parametrization
- Fix self-intersections in 2D parts
This option affects the presence of self-intersecting facets in 2D parts. This can lead to artifacts in rendering. When this option is enabled, during unwrapping presence of self-intersections is checked, and an attempt of resegmentation is made with the purpose to remove self-intersections. This procedure may take a few iterations and considerable time but it is recommended for the complex bodies.
Without checking (option is disabled)
With checking (option is enabled)
- Remove holes in 2D parts (is valid only for the Projection method).
When this option is enabled, an attempt to merge the large and small 2D parts will be made. It will require to reduce the number of small 2D parts.
