i really like the look of mixed media drawings that has been done originally by hand but i don’t have the time to draw it by hand and then scan it and so on… so please if you know a way to have a computer generated drawing look hand drawn… i would really appreciate it if you would share it here thanks check out his videos, they are great and if you skim through, they go into using PS & IAhttp://brentchamberlain3d.blogspot.com/ 1. Plot it as a PDF (or I guess you could scan it too) 2. Put it in Photoshop and save it as a JPEG 3. Take the JPEG and apply a Filter to it. Fliter ->, Distort ->, Glass. You can play around with the settings to make it more or less squiggly to your taste. 4. Save it as a PDF (or print) There is an AutoCAD plugin that will turn all lines into shaky handrawnings. I assume most apps have something like that. Here’s a random app that does that. The results (that I’ve seen) have all been universally comic and cheesy. Your mileage may vary. Export to .eps. Duplicate drawing 3 times. Click styles ->, Pencil & Ink or whatever. Put a different pen/pencil style on each of the three copies. Play with line size to make sure none of them look tooo comical. Weld lines together if necessary. Transparency ->, Multiply each layer with darkest layer ontop. Play with color and transparency. Nudge each layer with the arrow keys til each layer is a few pixes off from one another. ???? profit. I prefer nathanoj’s suggestion. Otherwise you’re in the land of skeuomorphs, where no architect should tarry. Use autodesk impression, it’s fairly easy to use.http://usa.autodesk.com/adsk/servlet/pc/index?id=9246650&siteID=123112 noone here has ever used ‘Squiggle’? while i agree with those who dislike the idea of turning something into a hand-drawn image instead of just drawing the damn thing…i think you could just import that .dwg into sketchup, tweak the style and voila!!!, another masterpiece. 1. Photoshop filters like watercolor filter etc. if you are talking about a rendered image… 2. If you are talking about a vector linework drawing, print to PDF, open it in illustrator and select your lines, and change your lifestyle to a pencil or other hand drawn line… Also, in illustrator you can adjust lineweights, and, to get the most rough look, tweak sone of your lines to be imperfect in cad before you bring it into illustrator, end of lines a little bit longer and a tiny bit ‘off’… Actually if it is a rendered view for really nice effects and results combine 1 and 2 above: layer a Photoshop filtered image with a vector overlay of a hidden line view of the render that you have brought into illustrator and applied a pencil line style to the linework… You can also slightly offset the pencil linework to make it look less perfect and also adjust certain lines you want to emphasize to be heavier handed while in illustrator… Make sense? Actually in Photoshop, there is also a function that let’s you isolate the edges as lines… I forget what it is called, but if you run that, and make that it’s own layer overlay, maybe you can skip the illustrator step… You can Aldo apply a filte to that photshop linework layer… a few rendering packages, like Final Render, have good pen-like modes. Otherwise, Photoshop transforms work well. There is a command called ‘napkin sketch’ starting in Arch Desktop 04, I believe. You definitely want to do a save as, because I’m pretty sure it turns your drawing into a new block with wavy, sketchy lines. I agree with everyone else, just bring the acad drawing into SketchUp, Photoshop, or Illustrator. ArchiCAD will produce any rendering in a variety of line weights, pencil types, pen types, etc. simply by using the Sketch Rendering option. It will look hand-drawn. It works good for presenting drawings that don’t appear too ‘finalized’ for your clients. why not print the drawing, place a beautiful sheet of double matte mylar over it, then trace it with your own hand………..beautiful!!!!!!! While I can appreciate where most are coming from when they say that this idea makes their stomach turn, there are, in fact, some times when making a cad drawing appear less rigid is a plus. I do a lot of residential and small commercial addition projects. After going out and doing a field survey of the existing conditions, I will typically come back to the office and place everything in cad. It’s easy and efficient to quickly layout everything. However, when it comes time to present a couple of options, it’s nice to have a way of communicating a schematic idea to the client. Hard lines scare the client and make them think that nothing can be changed. They look too much like construction drawings. When I have the time, I always prefer to throw some trace over the hardline drawing and do a quick ‘fat pen’ sketch. But sometimes, I don’t have that time. Options mentioned above help in that regard. Source.
