1 in DWG·DXF coordinates does not always mean 1mm. Compare the unit settings in the original drawing with known reference lengths. For files without or incorrect unit information, the actual size cannot be determined based on measurements alone.
Some drawings may contain manually altered dimension text. Rather than relying solely on the displayed text, measure the actual geometry; if necessary, compare the displayed text with the actual measured value in the dimension list.
Measure the distance between two points
Type "DIST" (or the alias "DI") into the command line and press Enter to measure the distance between two points. You can also use "MEASUREGEOM" (alias "MEA") to measure distance, radius, angle, or area.
Open the drawing in the viewer and zoom in sufficiently on the area to be measured.
Enable object snap (F3). Select the appropriate snap type—such as endpoint, midpoint, or center—to specify precise points.
Run DIST and select the first point, then the second point.
Review the measurement values displayed in the command line and ensure they align with your drawing units and reference lengths. Press the Esc key to exit an active command.
Verifying area and object properties
Run AREA or AA and follow the command line instructions to specify boundary points or select a supported object. Area should be interpreted as the square of the drawing unit. For example, if the coordinate unit is mm, the unit of area is mm². To add or subtract several boundaries, use Add (A) and Subtract (S); check the centroid and moments of inertia with MASSPROP.
Verify whether you are measuring a closed boundary and check for any holes or areas that should be excluded. Manually "closing" open lines or improperly connected boundaries can lead to an inaccurate area calculation. You can also cross-reference these values with the length and area data displayed in the object properties.
Print to PDF and check scale
PLOT (aka PRINT·EXPORTPDF) opens plot settings and outputs them to PDF. Output is the process of expressing a drawing as PDF, and is distinct from saving the original editing data in DWG/DXF.
Select the model or layout tab you wish to print, then execute the PLOT command.
Define the paper size, output area, and scale. Also, adjust black-and-white/grayscale settings and line weights to meet the required standards.
Check for any clipped elements, text, or line-thickness issues in the preview before saving as a PDF.
For outputs requiring accurate physical dimensions, please verify the known lengths and paper size. When printing on paper, also check the "Fit to page" setting in the PDF print dialog.
Also supports exporting all layouts into a single PDF file.
Modified drawings can be saved as DWG or DXF files under a different name, allowing for comparison with the original versions.
Measurements and on-screen output alone do not guarantee actual machining quality or safety during equipment operation.
