Evaluation report of the hottest microcomputer 3D

2. product manuals and help documents

3D CAD systems are more complex than general 2D systems, and using 3D for design is not very familiar to many designers. Therefore, the software design manual, training tutorials and help documents are very important for designers to master the use of software as soon as possible

among the software participating in the evaluation, solidworks2000 has fully localized use tutorials and training manuals, and the help has also been fully localized. Among them, the use tutorials also provide an electronic version in PDF format. Solidedgev8 provides user manuals in English and help in HTML format, as well as tutorials containing dozens of examples. Inventorr2 is more distinctive. In addition to providing user manuals and help, it also provides a help tool with multimedia and animation display - design experts, which can prompt users to complete various operations step by step. Several domestic software gscad98, intesolid98 and CAXA three-dimensional electronic drawing board 2000 provide user manuals, learning tutorials and help

3. user interface

the user interface design of software is very important for the ease of use and operation of software. The software participating in the evaluation basically adopts the windows style interface design, including menus, toolbars, dialog boxes, pop-up menus, etc., which can customize the position of windows and toolbars. Solidworks2000, solidedgev8 and CAXA three-dimensional electronic drawing board 2000 can also flexibly set the content and appearance of menus and toolbars. Intesolid98 has designed a command window similar to AutoCAD style that can be opened and closed, which can be operated directly with various system commands. In addition, solidedgev8 uses a prompt bar to replace the dialog box

using the multi document technology in windows, you can open multiple files, such as parts, assemblies, engineering drawings, etc., in the same application when using the 2-element refrigeration system, support drag and drop operations between different documents, and simplify the operation process. Among the participating software, solidworks2000, inventorr2, gscad98, solidedgev8 and intesolid98 adopt multi document technology

now 3D CAD software has generally adopted the dynamic guidance technology. When the cursor is at some specific position, it can display different cursors and graphics according to the current command state, the type and relationship of geometric elements at the cursor position, and guide the designer to design. In engineering drawing design and sketch design, using dynamic guidance technology, we can automatically capture the key points of geometric elements, such as endpoints, midpoint, and the positional relationships between geometric elements, such as horizontal, vertical, tangent and so on. When dimensioning, we can intelligently identify different dimension types, such as linear dimension, angular dimension, diameter and so on. In 3D design, points, lines, faces and features on geometric entities near the cursor can be automatically recognized as the cursor moves, helping to quickly and accurately pick up various geometric elements

another interactive technology to improve design flexibility is dynamic drag and drop technology. In 2D design, various geometric elements in 2D graphics can be dragged dynamically, and the graphics can change dynamically according to the added dimensions and constraints. Some software in 3D design can be dynamic in the modeling process
