@Last Software has updated its SketchUp 3D design software for Mac OS X to version 2.2, which adds expanded drag-&-drop capabilities and a new texture palette to the Apple Colour Picker that enables creation and management of custom material libraries. SketchUp is a 2D drawing tool that extrudes designs into 3D that the company claims does not require traditional CAD techniques. Users can now drag-&-drop images right from iPhoto into a SketchUp model for use as backgrounds or textures. And drag-&-drop support for a wide range of raster image types such as PDF, PSD, PICT, EPS, TGA, SGI, and BMP has been added. Version 2.2 adds a Colour By Layer feature for assignment of a material to a layer. SketchUP 2.2 also adds customizable keyboard shortcuts; an editable value control box; export options for DWG, DXF and 3DS formats; enhanced template support; drawing style preferences; vector printing and PDF output from Wire frame and Hidden Line display modes; and a plug-in for RIB export. The software costs $495 (around £307). Upgrading info, a free demo, and the RIB plug-in are available at the product Web site.
