Question 1

What is a DXF file?

Accepted Answer

DXF (Drawing Exchange Format) is a CAD exchange format commonly used for 2D laser, CNC, and plasma cutting. Sheet2Nest supports ASCII DXF files with entities such as lines, polylines, arcs, circles, ellipses, and splines.

Question 2

How can I view a DXF online?

Accepted Answer

Go to the Sheet2Nest DXF Viewer, upload your .dxf file, and the geometry renders in the browser with zoom, pan, and part detection. No account is required to view and analyze the file.

Question 3

Can I view a DXF without AutoCAD?

Accepted Answer

Yes. The Sheet2Nest DXF Viewer is designed for viewing and analyzing DXF files online without AutoCAD or a desktop CAD license.

Question 4

Is the Sheet2Nest DXF viewer free?

Accepted Answer

Yes. Viewing, analyzing, inspecting parts, and downloading individual parts as DXF or SVG do not require an account. Signing in is only needed when you continue into Sheet2Nest nesting.

Question 5

Can I download individual DXF parts?

Accepted Answer

Yes. Each detected part can be exported as its own DXF file containing only that part's geometry (outer contour, holes, and related cut paths).

Question 6

Can I download a DXF part as SVG?

Accepted Answer

Yes. Each detected part can also be downloaded as an SVG with a correct viewBox and aspect ratio for that part alone.

Question 7

How does Sheet2Nest detect parts?

Accepted Answer

Sheet2Nest identifies closed contours as parts using the same parser and geometry rules as the nesting product. Contained closed shapes become holes. Open contours are reported but not classified as valid nestable parts.

Question 8

Why was my DXF part not detected?

Accepted Answer

Common causes include open contours, overlapping or broken geometry, binary DXF (unsupported), or title-block frames that confuse outer boundaries. Ensure outlines are closed polylines or equivalent closed entities and export ASCII DXF.

Question 9

Can I use DXF files for laser cutting?

Accepted Answer

Yes. DXF is a common input for laser cutting. After reviewing parts in the viewer, you can nest them in Sheet2Nest and export layouts for cutting workflows.

Question 10

Can I use DXF files for CNC cutting?

Accepted Answer

Yes. Closed DXF part geometry is widely used for CNC and plasma sheet cutting. Sheet2Nest detects parts and can hand them into nesting for sheet placement.

Question 11

Can I send my DXF directly to nesting?

Accepted Answer

Yes. Click Nest These Parts after detection. If you are signed out, you sign in once; Sheet2Nest restores the detected parts into the existing nesting wizard so you do not upload the DXF again.
