An "Out of memory (swap device may be full)" error message is returned when attempting to generate a Hidden Line (HLN) (aka: Export Visible Edges) file.MicroStation seems to "hang" when processing the Hidden Lines.
Use Key-in: Edges Advance, enable "Facet All Surfaces" and "RemoveSmooth Edges within SmartSolids <(>&<)> Facets".The Hidden Line system can, at times, take a long time and/or use up alot of system resources. MicroStation has some tools that can be usedto speed up the process and otherwise avoid problematic solid elementsin a given file. Edges Advance contains some tools that are notavailable in the normal edges tools.With Regards to ACIS solids (in/from DWG files):If Solid data is ACIS solids (typically solids generated in AutoCAD).ACIS solids cannot be processed as cleanly as MicroStation nativesolids, also known as "ParaSolid". ACIS solids use up much more memorythan ParaSolid solids generally do. This could cause the Virtual Memoryto be used up quickly.Starting with MicroStation 2004 Edition 08.05.02.27...There are new tools added to the hidden line system. They can beaccessed with the following key-in:Key-in: EDGES ADVANCEThis opens a dialog similar to the Hidden Edges dialog, with followingadded settings:-Remove Smooth Edges within SmartSolids and Facets.-Expand Custom Linestyles.-Expand Hatch.-Facet All Surfaces.To get better and/or faster results by lowering the memory overhead,enable "Facet All Surfaces".This setting will cause MicroStation to facet the surfaces of the solidsinstead of trying to process the solids (and intersections) itself.To get cleaner results, that will remove the faceted edges, enable"Remove Smooth Edges within SmartSolids <(>&<)> Facets".Notes:-These tools are currently in Beta form so results may vary. Thesefunctions are fully functional in MicroStation V8 XM Edition.-There are extra "Tiling" options in MicroStation V8 XM Edition tofurther help avoid memory limitations.Other possible Solutions:-Increase Page file (Virtual memory).-Move Page file to another drive.-Increase Physical Memory (RAM).
