Example
A line from (0, 0) to (10, 0) measures 10 drawing units. The viewer reads the DXF unit code when present; when it is absent, measurements are labelled as drawing units.
How it works
A local worker parses ASCII DXF. No scripts, external references, images, fonts or network resources in the file are executed or fetched. This viewer does not open DWG or binary DXF.
Questions
Does this viewer support DWG?
No. This tool opens ASCII DXF only. It does not decode DWG or binary DXF.
Why are some entities missing?
The viewer draws only the entity types listed in its supported-content section. Other entities are reported by type and count; they are not silently approximated.
Are measurements in millimetres?
Only when the DXF declares millimetres. Otherwise the viewer uses the declared unit or labels measurements as drawing units.
