Using CAD Drawing Studio
Choose drawing units and page size, create geometry and organize layers. Save native JSON for editable fidelity, then export a supported drawing format and review its unit and text limitations.
Changing unit labels does not convert existing geometry. DXF imports support a strict planar R12 subset; exported dimensions become linework and labels rather than associative dimensions. PDF and DXF text have ASCII limits, fitted PDF is not 1:1, and unsupported large 1:1 pages are rejected.
Choose editable CAD geometry or a drawing exchange
Native JSON: preserve the tool's supported editable entities, layers and settings.
SVG: share supported drawing artwork, including text that needs a suitable Unicode renderer.
R12 DXF: exchange the strict planar ASCII subset; dimensions become linework and labels.
Vector PDF: choose fitted or supported actual-size output and inspect page and text limits.
Practice: a small dimensioned outline
Choose units before drawing a simple rectangle and adding a dimension.
Organize it on a layer and check the entered coordinates.
Save JSON before exchanging DXF or printing. Confirm the output's scale and labeling rather than relying on the file extension.
This is an authored drawing exercise, not a measured part or a certified fabrication drawing.
CAD exchange questions
Will changing the unit label convert my existing geometry?
No. Relabeling units does not rescale existing coordinates. Establish the intended units and review dimensions explicitly before using the drawing elsewhere.
Is every PDF 1:1, and will DXF preserve editable dimensions?
No. Fitted PDF scales the drawing; actual-size output rejects unsupported page sizes. DXF dimensions are exported as linework/text rather than associative objects. PDF/DXF text also has ASCII limitations.
