Dpi resolution
When importing pdf files, you can change the default resolution in dpi of the image, which is produced by the conversion of the current pdf file to image.
In case of large files, the value of 200 dpi
may be inadequate and some details will not be visible. As a result, you won’t
be able to measure correctly. Increase the resolution to 300
dpi, for example, and use the button ‘Load and preview current’ to see how the drawing will
appear when imported in the project.
Notice that in case of over-increasing the
dpi value, files become larger and you cannot process them easily.
