Modeling Clay Tool for Rhino ShipsSensAble Technologies, Inc. (Woburn, MA) says ClayTools for Rhino 1.0 lets designers use their sense of touch to create organic shapes and add sculptural details, handcrafted modifications, complex blends, and embossed textures to existing Rhino NURBS models.
Unlike traditional modeling tools, the ClayTools system uses a virtual clay metaphor that removes the constraints of technical modeling, offering speed and creative expression. The system includes the PHANTOM Omni device—a 3D interface with force feedback. Users work fast because they model virtual clay. The system is easy to learn and use.
Designers can create models using their favorite tools in Rhino, and then import their models into the ClayTools system. Imported Rhino models can be used as reference or converted to virtual clay—either in total or selected parts. The PHANTOM Omni device allows designers to smudge, smooth, carve, and tug to add details, blends, and textures that are challenging to achieve with traditional modeling tools. Models can be output to RP and used for casting, or imported back into Rhino to finish the model and export for rendering, RP, or CAD/CAM.
Price: $2,795 (includes ClayTools and PHANTOM Omni device); $1,995 (software only). For more information, visit sensable.com.

Leica CloudWorx for AVEVA PDMS for Better Plant RetrofitsFollowing up on a strategic collaborative alliance for developing laser scanning solutions, Leica Geosystems (Heerbrugg, Switzerland) and AVEVA (Houston, TX) have jointly announced Leica CloudWorx for AVEVA PDMS.
This new software application integrates with AVEVA’s powerful Plant Design Management System (PDMS) to enable AVEVA customers to take advantage of Leica’s point cloud technology directly. Here, users can easily review, clash, measure, and modify proposed retrofit designs based on accurate geometry of existing conditions as captured by High-Definition Surveying (HDS; a.k.a. laser scanning). The net benefit is better overall project results.
Previously, PDMS users had to apply various import/export tools and data format converters in conjunction with another stand-alone Leica application, Cyclone. The new, integrated solution accesses PDMS directly through AVEVA’s new Laser Model Interface. Leica Geosystems is said to be one of the first companies to take advantage of AVEVA’s new, open interface technology.
Users can take advantage of data captured by versatile time-of-flight (TOF) laser scanners and ultra high-speed phase-based laser scanners, including Leica HDS3000, HDS2500, and HDS4500 laser scanners. Intuitive tools in the new application make it easy for users to access and manage laser scan databases with a convenient ScanWorld manager. Visualizing and selecting specific areas of point cloud data to submit to the PDMS interface is also made easy by handy user-defined limit boxes, cut planes, and cloud slices.
