I'm working on a javascript application that uses the MarkupsCore extension to create markups on a floor plan in the Autodesk Forge Viewer. I want to export a .dwg file from the viewer, but I also want the file to contain those markups. I basically know how to export the .dwg file, but I don't know how to combine the svg markups with the file before exporting. Is this even possible? If so, how?
The markups as stored/saved as SVG files, which is a XML-based format to describe geometry. And I believe you know that :-) I did a quick search and found a few articles about SVG to DXF conversion, where DXF can be imported and converted into DWG via AutoCAD engine (or Design Automation API).
So a route would be: show DWG model, add markups, save as SVG, convert to DXF, convert again to DWG, merge into original DWG. I don't have such a sample nor can guarantee it will work and be accurate, sorry.
