WrapR allows you to export selected faces in SketchUp to be UV unwrapped. WrapR will NOT export geometry that is in a group or component. It strictly deals with raw mesh data.
The WrapR for SketchUp extension can only export the following:
The WrapR for SketchUp extension CANNOT export the following:
This guide is to serve as a reference for exporting 3D meshes from SketchUp using the WrapR for SketchUp extension.
Use SketchUp's Select tool to select the mesh you want to send to WrapR for UV mapping. If you have any groups or components in your selection these will be ignored during export.
To send your selection to WrapR use the File > Send to WrapR... menu, the toolbar button or context-menu.
Immediately after sending your selection to WrapR the WrapR application will open and begin to process the 3D mesh. After processing the the UV unwrapping will run if any seams are detected.
To mark an edge as a UV seam you can use the UV Seam tool. Any edge that can be marked as a UV seam will turn green when you hover over it. Left clicking the edge will mark it as a UV seam and it will remain green.
To mark a path as a UV seam you can use the Smart Path Seam tool. To toggle to Smart Path mode press CTRL while in Single Edge mode. In Smart Path mode you can click the first edge as the start point and the last edge as the end point. Smart Path will then take the most logical path between points.
Marked Paths remain highlighted orange until to press ENTER to commit the selection. The selection will then be marked as a UV seam and will become green.
To mark a loop as a UV seam you can use the Loop Seam tool. To toggle to Loop mode press SHIFT while in Single Edge mode. In Loop mode the natural loops in your mesh will be highlighted in purple when you hover over them.
Left clicking on a highlighted loop will mark it as a UV seam.
This guide is to serve as a reference on how to mark ,unmark and select UV seams in WrapR. This extends the capabilities available in SketchUp to give you total control over your UV maps.
To select edges in WrapR you can use the Edge Select tool, or activate it via SPACEBAR, and use the following techniques:
You can also extend the Edge Select tool using modifier keys:
The Edge Select tool allows you to select loops and paths by:
To cut edges in WrapR you can use the Cut Edge tool, or activate it via C, and any selected will be cut and the 2D viewport will display the result.
To weld edges in WrapR you can use the Weld Edge tool, or activate it via W, and any selected will be welded and the 2D viewport will display the result.
