To generate 2D drawings from an IFC model in Bonsai, use the bonsai.bim.module.drawing operators to create orthographic camera projections for plans, sections, and elevations, then sync your IFC data before outputting the results as printable SVG sheets.

Bonsai drawing outputs often appear empty or broken when the orthographic drawing camera is not activated or the IFC data is not synchronized. Enforcing correct drawing view guardrails and module usage ensures a complete and reliable generation pipeline.

Yes, you can add typed annotations including text, dimensions, levels, hatches, and hidden lines to Bonsai IFC drawings. The annotation workflow integrates these elements directly before composing the drawings into titleblock-based sheets.

Yes, you need InkScape installed to export your composed Bonsai SVG sheets to PDF or DXF formats. The drawing pipeline generates the SVG sheets natively, but relies on InkScape for the final printable document conversion.

OpenCASCADE and Freestyle are optional linework modes in Bonsai that determine how 2D line geometry is extracted from the 3D IFC model. Selecting the appropriate mode affects the generation of orthographic drawing projections and hidden lines.

To compose multiple Bonsai drawings onto a single sheet, generate your individual plan, section, and elevation views as orthographic projections, then use the sheet composition operators to assemble them into a titleblock-based SVG layout.
