View, measure and resize a DXF drawing
Open a DXF or SVG drawing, see its layers, measure between points, set the unit and resize it, then export DXF, SVG or a PDF page at the real size. Images can be traced to outlines too.
View layers, measure, set units and resize, then export. Your file stays in your browser.
What it opens
Text DXF and plain SVG, both read in the browser. A PNG or JPEG can be traced to outlines at a width you set, which is the route in when all you have is a picture of the part.
Layers arrive with their names and visibility. Measurements snap to endpoints, centres and the ends of arcs rather than landing wherever the cursor was.
Units are the whole problem
DXF declares its unit in an optional header variable, and plenty of files leave it out. SVG has no unit unless the root carries a width or height with a real length on it, and a bare viewBox is pixels at 96 to the inch by convention.
So the workspace tells you which case applied rather than picking one quietly, and lets you assign the unit yourself. Every measurement and every export follows from that choice, which is why it is asked for rather than assumed.
What comes out
DXF, which is read back and checked before it downloads. SVG with real physical dimensions on the root. Or a PDF page sized from the drawing itself, with layers as optional content groups a reader can toggle.
Text, dimensions and hatches are refused rather than dropped silently. The DXF guide explains what the format carries.
