![]() objects imported from Cinema4D or 3DStudio, which were modeled in a completely different scale and are over-detailed compared to their significance in the ARCHICAD model. ![]() objects from other applications - e.g.(See details in TechNotes/How to put custom images to default bitmap people) Using Alpha Channel, you can achieve proper shadow casting with this object. You can even use your own images to customize this object. Instead of using trees, you might consider using the "Tree Bitmap" object, which is a single polygon with an image applied as a texture. Trees and plants - consider that each leaf is an individual polygon - and if shadow casting is on, then leafs cast shadow on each other, creating a vast amount of shadow polygons.are not over-detailed.Įlement types that most typically contribute to large number of polygons: The resolution of elements that had been created with the Magic Wand tool can be controlled by the Magic Wand settings (prior creation).Curtain walls have a Model View Option for "Full" or "Schematic".Also, some elements have extra fittings that you might also turn off temporarily - e.g. You can set it as low as possible without having a major effect on what you see in 3D. (Note that you can set the detail level in the the Pol圜ount palette of the Polygon Counting tool) Similarly, curved objects typically have a "resolution" parameter. You can temporarily set this to "Simple" instead of "Detailed" when working in 3D. Some objects have different 3D detail level settings.Use the Marquee tool or the 3D Cutting Planes to show only a part of your model. ![]() You can also set here which stories you want to see - you might not need all of them all the time. #Screen marker too slow windowsUse the Filter elements in 3D feature (It's in View menu/Elements in 3D view) to turn off element types you do no really need - You might not always need Lamps, Curtain Walls, sometimes not even doors and windows when working in 3D.Save a Layer combination that you use for working in 3D interior walls and furniture, site improvements, etc. ![]() layers of elements that you do not even see in 3D - e.g. Make sure you turn off unnecessary layers, e.g.Library parts are listed by object type - you will many times find that library parts make up for 80-90% of the projectįirst of all, make sure that only elements that you really need are displayed in the 3D view: The Pol圜ount palette will list ARCHICAD elements by type, and displays the number of polygons each element type represents in the project. #Screen marker too slow downloadThe easiest way to check model size is to use the Polygon counting tool, which you can download from the "ARCHICAD Downloads" site ("ARCHICAD Goodies" in earlier versions), available from ARCHICAD's help menu. As a rule of thumb, a model is "large" when polygon count reaches 1 million, and the performance problems turn severe in the 3-4 million region. Note however, that it is not the only contributing factor. The most typical reason for poor 3D performance is the large number of polygons in the 3D model.
