Rendering to appear more "sketchy"?

[saviersrd]

Hey all,

I'm new to Revit Architecture and I have a quick question... when rendering in 3D, is there a way to make the drawings appear more sketchy? For example, lines do not have to intersect perfectly..have some lines overlap - just like how a free-hand drawing would look like?

Thanks in advance.

Not in Revit--but you can use Photoshop or Piranesi
to get some nice softer/hand-drawn effects.

Check out Piranesi---it's a really nice program that understands 3D
depth of a perspective model, and even inherits materials from the
original 3D model.

See attched images for example of Piranesi's ability.

cheers...........

having last used Piranessi YEARS ago, i'm curious if you can do the sketchy look like in the second view but without it having the bumpy paper look?

thx...

Yes, the bumpy look is a paper choice.

Cliff, what’s your Revit to Piranesi workflow? 3D DWG? Thanks.

[saviersrd]

Thanks for the reply. I have Photoshop but not Piranesi... I'll look into that.

Cheers

If you're on subscription you can download Autodesk Impression 2 for free. It has lots of sketch, paint, watercolor, etc. tools to create that look.

I agree with with Partriks,
The Autodesk impression program is good and it will take a revit model easily.
Pretty simple to learn as well.

If it's just a sketchy drawing style you are after, many architects still like Squiggle.

Personally I'm not a fan of the sketchy look but apparently I'm in the minority ;)

Cinema 4D has a Sketch & toon plug-in which also allows this sort of thing and I daresay 3dsMax will have something similar which act on the model rather than a 2D export.

It will be nice if/when Revit can export a file with layers based on materials so that in Impression you can assign colors easier and have them update automatically when the file is revised and reimported. Layers by category don't go far enough.

The problem with computer drawings done in the earlier phases of design is that they look complete and that can be enough for some clients to, more or less, freak out. They think the design is done (it looks done) when it's far from it. If we had a way to represent graphically the level of percieved design completion it would go a long way to helping our clients understand where we ar in the process.

Squiggle is good for this and Napkin Sketch works okay but the workflow from Revit to these is unacceptable. I need to play with Impression more to see how I can get it to work with as little effort as possible.

That's exactly what I was looking for! Thanks!

You can get a very sketchy look using sketchup. You can create your 3d model in Revit, then export it to cad. Then open Sketchup and import the cad drawing. Sketchup is a very handy 3d software to model very quickly solids and you can find a variety of sketchy styles and cool materials (it is a free software, by the way).

After you are done transforming your model you can export it into Revit and make the sketchy look part of your construction documents.

I'll look into that. Thanks.

Saviersrd-

If you are on subscription, you will do yourself a disservice if you don't at least check out impression also. As the others have noted, it is free to subscription members and is easy to learn.

The workflow is where Impression excels. Sort of -- i should say. Impression currently reads only dwg files, but you can easily set up a few quick views in Revit, export to dwg and bring right into Impression. If your Revit geometry changes, simply export again and update it.

It's not a bad little program....too bad not many people know about it or use it.

I do not have subscription =(

You can bring in DWF files into Expression too though I don't know if you can do the same things with them or not.

kingjosiah - Any chance I can get you to share the .irf file of that impression example? That looks like what I'm trying to do and it seems you done it really well.

[kingjosiah]

Greg-

I tried uploading the irf file but was unable to since it is not a valid file type. Can you PM me your email address and i'll send it your way?
