cad system

基本解釋

Additionally, the many complex features of a 3D parametric CAD system are supported by the PDM system available from the same developer.
況且，3D參數(shù)化CAD系統(tǒng)中諸多復雜的功能通常都被由相同一群人開發(fā)的PDM系統(tǒng)所支持。
When it comes to 2D/3D, questions become more complicated – type of data, CAD system, purpose of share, precision, etc. – this is only a short list of questions.
當共享對象是2D和3D信息時，問題就變得更加棘手了，要考慮到數(shù)據(jù)類型、CAD系統(tǒng)、共享的目的、精確程度等等，不一而足。
However, as soon as functional requirements are going beyond simple CAD file management or going beyond support of a single CAD system / environment, the implementation becomes crappy.
不過，一旦功能需求超出了簡單CAD文件的管理或單一CAD系統(tǒng)/環(huán)境的范圍，那么實施就變得相當麻煩。

Students in the program learn to use computer-aided-drafting (CAD) to design a photovoltaic system, they learn about the sorts of issues that come up when designing such a system, and they learn about the installation and maintenance of such systems.
