@Last Software is now shipping SketchUp 4.0, a new version of the company's 3D design software for Mac and Windows. The software was officially launched yesterday at the Macworld Conference & Expo in Boston.

Major new features in SketchUp 4 include ‘Follow Me’, which enables users to push or pull a surface along a path. ‘Texture Tweaker’ allows users to stretch and otherwise manipulate any texture or photo along any continuous surface.

‘Face Me’ makes 2D models of people and landscaping elements appear to be 3D, and makes them face the direction of viewer regardless of the orientation of the model. ‘The Intersector’ is a Boolean model generate that allow users to create complex intersected images quickly and easily.

Also new in this release is an interface for Ruby, a scripting language that can be used to automate tasks, which @Last describes as similar to the lisp language used in the popular 3D engineering tool Autocad.

SketchUp 4.0, which won a Macworld Best of Show award this week, costs $475 (around £261) to purchase as a download or $495 (£272) on CD. Upgrades for existing customers cost $95 (£52) per license.
