How can a PDF file be imported into OpenBuildings Designer for further editing in the same?
This functionality was implemented in OpenBuildings Designer Update 10 as well as in MicroStation update 17 as a technology preview.
You can import vector data available in PDF files as DGN elements (such as lines, polygon strokes, curves, polygons, text and so on).
Vector elements are represented as drawing elements.
As delivered PDF files will be imported or merged into DGN files as raster images, this is to maintain consistency with existing workflows while this feature is in Technical Preview.
To enable the import as vector function the value of variable MS_IMPORT_USINGADOBEPDF must be changed from 1 to 0.
After changing the value for this configuration variable, restart your session for the changes to take effect.
