The 3D ACIS Modeler (ACIS) is a geometric modeling kernel developed by Spatial Corporation (formerly Spatial Technology), part of Dassault Systèmes.ACIS is used by software developers in industries such as computer-aided design, computer-aided manufacturing, computer-aided engineering, architecture, engineering and construction, coordinate-measuring machine, 3D animation, and shipbuilding.
The table below provides an overview of notable computer-aided design (CAD) software. It does not judge power, ease of use, or other user-experience aspects. The table does not include software that is still in development (beta software).
CAD standards are a set of guidelines for the appearance of computer-aided design (CAD) drawings should appear, to improve productivity and interchange of CAD documents between different offices and CAD programs, especially in architecture and engineering.
3D rendering of spoons in CAD software. In 1981, the key products were the solid modeling packages—Romulus (ShapeData) and Uni-Solid (Unigraphics) based on PADL-2—and the surface modeler CATIA (Dassault Systèmes). Autodesk was founded in 1982 by John Walker, which led to the two-dimensional system AutoCAD. [22]
Whereas in a conventional hand drawn technical drawing, if a mistake is found, or a modification is required, a new drawing must be made from scratch, the 2D CAD system allows a copy of the original to be modified, saving considerable time. 2D CAD systems can be used to create plans for large projects such as buildings and aircraft but provide ...
This is a list of all Internet Relay Chat commands from RFC 1459, RFC 2812, and extensions added to major IRC daemons. Most IRC clients require commands to be preceded by a slash (" / "). Some commands are actually sent to IRC bots ; these are treated by the IRC protocol as ordinary messages, not as / -commands.
In the maximum-2-satisfiability problem (MAX-2-SAT), the input is a formula in conjunctive normal form with two literals per clause, and the task is to determine the maximum number of clauses that can be simultaneously satisfied by an assignment. Like the more general maximum satisfiability problem, MAX-2-SAT is NP-hard.
A force there would block VC avenues of escape to the south. Three LZs, Red, White and Blue, were selected 4 miles (6.4 km) east of Route 1 and roughly 1 mile (1.6 km) inland from the coast. LZ Blue, about 2 km west of Green Beach, was the southernmost of the LZs. White was 2 km west northwest of Blue, while Red was 2 km north of White.
