What this tool does
For a colleague using an older AutoCAD edition, choose the target year and create a simplified 2D copy. The converter reads geometry and rewrites entities and tables, rather than only changing the header. Blocks are exploded and curves become segments. Associative dimensions, hatches, line types, layouts, 3D solids and special objects are not preserved.
Check with a sample file
The sample plan has a 600 × 400-unit rectangle, a 100-unit opening, an arc and EditFull text. In the PDF, the rectangle is 432 × 288 points: the 3:2 ratio should remain. Compare input and output using these values; the file is not a construction drawing.
Frequently asked questions
Is my drawing uploaded?
These CAD tools process files in your browser. Selecting a file does not upload it for server conversion.
Does it work with DWG?
Conversion uses ASCII DXF. Use Save As or Export to DXF in your CAD application. The version inspector accepts DWG but does not convert its contents.
