Transcript Why OMF?
Experiences with building OMF applications Developing applications for the AEC Market using OMF By Gamal Kira, G.E.M. Team Solutions, Germany G.E.M. Team Solutions • Custom development for the AEC Market • More than 10 years experience in CAD/AEC development • Part of the ADT development team since 1996 (ADT 1.0) • More information on web site: www.team-solutions.de When we use OMF? • Applications for AEC to work with ADT • Applications for plain AutoCAD • Experienced C++ developers who are new to AutoCAD Resource Manager • Easy to support multiple languages • Easy switching languages (registry setting) UI and other Tools • • • • • • • • Registry mechanisms Layerkeying Prompts, Editboxes (Distance, Angle, etc...) Possible to add property pages to existing property sheets Units AecGeCompCurve2d, AecGeProfile Aec::... Streams Display System • Lots of opportunities • Flexible Custom Formwork Application • Paschal GmbH (www.paschal.de) needed an application for complex formwork planning • We suggested using ADT • Project started in Summer 2000 • Mr. G. Schmitt (Paschal) is the Product Designer Design Center • AEC Content (commands, ...) • Preview window (view dependant) AEC Modeller • Fast facetted modeller • Used for pour object and in UI Anchors • Special relationship between objects • Basically designed for location anchors, but can be used for more • Owner/Ownee relationship has special behaviour in copy & delete • ... demo Relationship Graph • AcDbObjectReactor derived class • Tracks (AEC) relationships within drawings • Some useful utilities can be used here -> getObjectsOfType GEM Doctor • Tool we developed along with our projects to see what‘s going on during an AutoCAD/ADT session • Pre-Release is available as a free evaluation version on our web site • ... demo Style Manager • We didn‘t use it yet, but it could be powerful (styles on the web etc...) Things to consider when using OMF • Base class for entities is AecDbEntity (derived from AcDbCurve!) • Base class for objects is AecDbObject Pros • Feature changes for free – Dialog pinning – AEC Feature changes – New utilities • • • • Resource Manager Streams Anchors Cloning etc. is taken care of Cons • New Release of AutoCAD, wait for OMF! • Compared to ARX difference between releases (2 -> 3.0) are quite significant. • help files could be more precise Résumé • For us, OMF was just the tool we needed to develop applications Questions?
