Markup Import and Markup Assist use machine learning to identify markups and provide a way to view and insert drawing revisions with less manual effort.
Markups can be imported as a PDF, JPG, or PNG and are overlaid on top of your drawing in the Trace environment. Markups in the imported file are automatically identified as text and revision clouds. Markup Assist lets you insert those identified markups into the drawing as geometry.
Markup Import
Use Markup Import to place a marked-up version of your drawing on top of the original file to make it easier to view and incorporate changes to your drawing. For example, if you have a PDF version of your drawing that has text and revision notes added, use Markup Import to overlay the revised drawing on top of the original. Or, if you have a printed version of your drawing that contains hand-written revision notes, you can take a photograph of the printed version and then import it as a JPG or PNG.
Imported markups are added as a new trace in the Trace environment. Use TRACEPALETTEOPEN to open the Traces palette and view a list of traces in the drawing.
The imported file is automatically placed and aligned on top of the drawing file in a new trace. The imported file can be a representation of the entire drawing or only a part of the drawing. If the imported file is not aligned correctly, you can manually align, move, scale, or rotate the imported file.
When viewing imported markups, you can change the background transparency to adjust the visibility of the imported markup.
Markup Assist
Markup Assist automatically identifies markups as text and revision clouds. After importing a markup, turn on TRACEVIEW to activate the trace mode that lets you modify the drawing itself.
Click an identified markup, then insert it as an mtext, mleader, or revcloud object. You can edit the text before inserting it or choose to copy the text to the clipboard. Inserted text, leaders, and revclouds take on the properties of the current layer.
Best Practices for using Markup Import
- Trace and Markup Import work best with 2D drawings. Markups are not easily identified in drawings that are 3D or have non-wireframe visual styles.
- Imported images are reduced to 4k resolution. It's recommended that imported markups do not exceed 4k monitor resolution or 144 dpi.
- When taking photographs of physical paper, ensure that the paper is brightly and evenly lit. Avoid shadows falling onto the paper, including folds and creases, and avoid taking photographs where the lighting is uneven across the extents of the paper. Shadowy or unevenly lit photographs will decrease the likelihood that the markup is successfully identified as being separate from the underlying drawing.
- When taking photographs of physical paper, do not include objects in the background other than the drawing page. If needed, crop the image to the physical page after the photograph has been taken. If the markup is only in a small area of the drawing, it isn't necessary to include the entire drawing in the photograph, but AutoCAD will generally do a better job of automatically aligning the photograph to the drawing when more of the paper is included in the image.
- When taking photographs of physical paper, avoid taking photographs of the page from an acute angle. As much as possible, take photographs from directly above the paper, with the camera pointed directly at the page. Photographs taken from acute angles will introduce distortion into the image after it is imported into AutoCAD, and AutoCAD will be less likely to automatically align these images to the drawing. Unlike distortions, rotation of the page in the image should not cause distortion and generally will not cause AutoCAD to be less successful aligning the image to the drawing. For example, it is not necessary for the "top" of the page to be the "top" of the image.
Best Practices for using Markup Assist
- Markup Import works best when the non-markup part of the imported file is monochrome or grayscale. For best performance, use imported drawings that don't contain colored lines or regions.
- Markup Import works best when the markup is made in a solid, opaque color that is not black or dark blue. Markup in black or dark blue colors, or markup that is not opaque (such as a colored pencil or a highlighter) will decrease the likelihood that the markup is successfully identified as being separate from the underlying drawing.
- Use high-resolution scans and photographs. Imported images with scaled-down resolution may reduce markup assist's effectiveness.
Web and Mobile
All Markup Import features are available in the AutoCAD web and mobile apps. The AutoCAD mobile app also allows you to import a photo directly from the device's camera. Go to and follow the steps on your mobile device to import a photograph of your markup.
