Tutorial 07

Export nozzle geometry as DXF.

Move the solved nozzle profile into CAD while preserving the solved geometry basis and export warnings.

What you will learn

How to export a solved nozzle contour through the current DXF Export Options dialog.

Prerequisites

A successful non-stale solve with valid chamber, throat, exit, and nozzle length geometry.

Steps

  1. Click Solve after final geometry edits. If an export button shows (stale), re-solve or be prepared to confirm a stale export.
  2. Open Review > Geometry and confirm throat diameter, exit diameter, chamber length, nozzle length, and contour type.
  3. Click the toolbar Export DXF button, choose File > Export DXF Geometry..., or use Review > Exports > DXF geometry….
  4. In DXF Export Options, choose an entity mode. Compatibility-safe DXF (recommended) exports LINE/ARC entities plus a controlled polyline fallback for reliable CAD import.
  5. Select the DXF units and options: Export centerline, Half profile (upper contour only), and Export construction / tangent points.
  6. Click Continue…, then choose a path in Export DXF Geometry.
  7. Read the DXF Export — Geometry Notes dialog. It summarizes exported entities and any geometry warnings.

Expected result

The selected folder contains a .dxf file generated from the solved project snapshot, not unsolved live edits. The status area reports the DXF entity summary.

Common notes

  • DXF export is blocked if the solve failed or the solved geometry is degenerate.
  • Stale export requires an explicit user choice. Use the PDF report with the DXF when reviewers need performance assumptions and warnings.
  • Verify units and scale in CAD after import, especially when handing geometry to machining or external review.
