( Cambridge, England) which had been retained by Dick Sowar's Spatial Technology (which had been founded by Sowar in 1986) to develop the ACIS solid modeling kernel for Spatial Technology's Strata CAM software. In 1985 Alan Grayer, Charles Lang and Ian Braid (creators of Romulus and Romulus-D) formed Three-Space Ltd. However, when asked, the creators of ACIS would simply suggest that its name was derived from Greek mythology (See also Acis).
According to a close source the name actually stands for Alan, Charles, Ian, Sowar, with Sowar coming from Dick Sowar, founder of Spatial Technology. The most popular version is that ACIS stands for Alan, Charles, Ian's System (Alan Grayer, Charles Lang and Ian Braid as part of Three-Space Ltd.), or Alan, Charles, Ian and Spatial (as the system was later on sold to Spatial Technology, now Spatial Corp). There are several versions about what the word ACIS actually stands for, or whether it is an acronym at all. 2.1 Supported Platforms and Operating SystemsĪs a geometric kernel, ACIS is a second generation system, coming after the first generation Romulus.ACIS is used to construct applications with hybrid modeling features, since it integrates wireframe model, surface, and solid modeling functionality with both manifold and non-manifold topology, and a rich set of geometric operations.
ACIS provides software developers and manufacturers the underlying 3D modeling functionality.ĪCIS features an open, object-oriented C++ architecture that enables robust, 3D modelling capabilities. ACIS is used by many software developers in industries such as computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAE), architecture, engineering and construction (AEC), coordinate-measuring machine (CMM), 3D animation, and shipbuilding. The 3D ACIS Modeler ( ACIS) is a geometric modeling kernel developed by Spatial Corporation (formerly Spatial Technology), part of Dassault Systemes. Have long wished for a setting that uses a physical geometry bounding box.Īctually ProE has always had an issue with the screen resizing withīounding box changes due to geometry changes which is also frustrating.īe happy to hear if somebody else has a technically more elegant solution.Windows 7 (and above), macOS and Linux ( Red Hat) Projections off these views but need to us 'partial view' to resize the box Sometimes have to redefine the reference point if geometry changes remove This gives aīounding box based on that spline. The work around I routinely use (since using ProE) is to use partial viewīUT draw a spline around only the the physical part geometry. The base problem is that the bounding box is defined by the furthestĮxtents of the spatial geometry and things such as a large radius gives anĪxis way off the physical model which the bounding calculation uses to make Have not seen a reply to this so I will give you my work around.

I have attached an image showing the issue. I hide the import feature but the selection box continues to be as large as the imported feature. The size of the block is small but the imported data that I used to build the block is very large. This makes it very difficult to select the correct view that you actually want to move. In a drawing I insert a general view and the view selection box will be so large that it ends up overlapping other projected views.
