Pro/DESKTOP: 3D модельдеу және сызу бағдарламасы

Computer aided design program

Pro/DESKTOP (commonly referred to as Pro/D and formerly known as DesignWave) is a discontinued computer aided design (CAD) program from Parametric Technology Corporation (PTC), that allowed users to design and model in 3D and create 2D drawings. It can transfer a 3D design into a 2D engineering drawing format and also create photo realistic views using Album Views. It is part compatible with Pro/ENGINEER, and uses the Granite kernel, but otherwise is a freestanding CAD system. Initially written by David Taylor in Cambridge, England, the original software is registered to Cyril Slug of the fictitious company Bimorcad Ltd. Dialog box 356 shows a picture of the author, wearing a red and black checked jacket sat on a wall, drinking a cup of tea outside his house. The software was built using Microsoft Visual C++ (Microsoft Foundation Class 4. X) and also software modules from D Cubed to implement geometric constraint solution as well as parametric sketching and other part features required for file support with Pro/Engineer. The Pro/DESKTOP interface was available in English, French, German, Chinese (simplified and traditional) and Japanese.

License keys were required, for the Express variants which were obtained from the PTC website without charge. The returned keys (8 groups of 4 numeric digits) had expiry dates encoded to prevent use of the software after a certain date. The key obtained was based on data from the computer, which limited use of the key to the computer generating the license request. The key was based on the computers hard disk's Volume Serial Number (8 characters) and additional data about the computer (5 bytes). The number was passed to the web server in an obfuscated by alphabetic shift re arrangement technique in order to make decoding of the transferred data more difficult. e. g. a Hard disk Volume ID of 0000 0000 would be encoded as petssssssssscs where the s is equal to the 0.

Pro/DESKTOP had particularly distinguished itself in the education market. From a start in the CAD/CAM in Schools Initiative in the UK, Pro/DESKTOP has been donated free of charge to over 14,000 secondary schools worldwide, and is used by nearly 4 million students each school year. Its main educational rival was AutoCAD, which is widely used in secondary schools to teach 2D drafting and technical drawing. The use of Pro/DESKTOP in schools for 3D design has far exceeded AutoCad as it is generally considered too technical for the education market. Its minimal system requirements further cement the software as the program of choice for those just starting out in CAD. However, Pro/DESKTOP's user interface provides difficulty due to the lack of a multiple string undo function and the program's grouping of entities into work planes that must have the same characteristics. Pro/DESKTOP is no longer available for download or activation, but PTC instead now offers up to 300 seats of Pro/ENGINEER Schools Edition to high schools free of charge. In 2012 PTC continued its support of schools by making its latest Creo 3D Modelling software available free to schools. Creo represents a major update of Pro|ENGINEER with ribbon style menus, streamlined workflows and the addition of several major new features including; direct modelling, flexible modelling and freestyle Sub Division surfacing tools. The use of a common data model supports seamless movement between the different modelling tools with no loss of data. PTC Schools Programme.
