CADSoftTools

We are using CADImport.NET to manipulate a large batch of dxf images for a customer. Included in this is a conversion to raster format and a pdf generation.

We are having some problems with thin lines disappearing when the resulting PDFs are printed. We are guessing that this is due to the lines being so thin that they sometimes dissapear in the printer rescaling process. We need to have some kind of workaround for this.

Things we are considering:
1. Use a higher resolution when converting to raster format (no idea if this works, probably not)
2. Somehow make all lines thicker in the rasterized image (how?)
3. Use some sort of autocad CTB-file (?) when converting (how?)

Other suggestions are much appreciated.

Best regards

Hello.
Please try the following:
1. Generating printing to the bigger paper format. This must affect printing rescaling process. Increasing the resolution when converting to raster format will only affect raster image. If the lines are seen on raster image then higher resolution won't give any results. Otherwise try higher resolution when convert.
2. Making lines thicker in source CAD file must affect printing. You can set thickness of any CADPenLine descendant object (CADLine, CADPolyline, CADCircle, etc.) by CADPenLine.LineWeight property.

Unfortunately AutoCAD CTB files not supported.
