Drawing conversion

Get outside drawings into Revit, at true scale.

Two converters for the two kinds of file consultants send. Both write a DXF in inches that imports into Revit at 1:1 — correctly scaled, with line weights and text intact.

CAD Converter

Clean up a consultant’s DWG or DXF into a Revit-friendly DXF.

  • Checks declared units against labelled dimensions before it scales anything
  • Black and white, purged, junk and MTEXT codes stripped
  • Welds linework so Revit can explode it

PDF to DXF

Turn a vector PDF sheet back into CAD — when a PDF is all you were sent.

  • Reads the drawing scale off the sheet, or calibrate from a known length
  • Keeps line weights, colours and text placement; text sheets stay 1:1 at 3/32″
  • One page, every page, or a whole set as one DXF with a layout per sheet

Which one do I need?

The consultant sent a .dwg or .dxfCAD Converter — always better than going through a PDF.
You only have a PDF exported from CAD, Revit or BluebeamPDF to DXF
The PDF is a scan or photo of a drawingNeither — there are no lines in a scan to recover. Ask for the CAD file.

In Revit, always import with Import units: Inch — never Auto-Detect.
