I have recently started experimenting with Impression, software developed by Autodesk. It gives AutoCAD drawings a hand drawn effect, which is ideal for presentation of concept drawings. The software is still in development, and has some bugs, the print quality from the software itself is poor for example.I have found, however that printing the final image to a .pdf file produces a better result or saving the image as a .jpg. Different styles can be applied to different layers so one can of a combination of effects.
