3d line drawings for hand rendering.

What is the best way to generate a 3D line drawing on a 24 x 36 paper for rendering by hand. I've tried sketch mode with pen and ink, and the hidden line mode with internal engine. Both of them are blurry when plotted and the hatch is a mass of dots rather than actual hatch. It looks OK from a distance but is poor when viewing up close.

I have saved a 3D hidden line view as 2dl drawing and then placed it on sheet for larger 2D views. Seemed to work pretty good because you can scale it without the jaggies appearing.

Which engine did you use?

And you can substitute a squiggly line type in the 2dl file to make it look more like a sketch, too....

Tom, I just used the Archicad engine and hidden line with no shading. I have not tried the squiggly line as suggested by Dwight but I thought you might be using this as a base for tracing over. The nice thing about the 2dl file if you want to use it as an end product is the fact that it is lines not pixels so you can edit out any lines that show up that you don't want like messy intersections etc.

Here's the thing. I don't want to trace over it, I just want to render it after it comes out of the plotter on a 24 x 36 sheet. I have an inkjet plotter, but I know it can plot finer lines than what I am seeing on the paper now.

I have been saving to a .jpg, then increasing the size of the drawing, which reduces the dpi. I may or not be doing the right thing to get what I am looking for.

How do you save to a 2dl. Is that a line drawing? like lines and arcs?
Something I can clean up in Archicad?

Out of time....gotta get some color on it. This client wants the hand drawn look and rendering rather than the photorealistic look.

You can save the 3D window out as a .2dl drawing if you use the Archicad engine and hidden line mode. They you open the .2dl file in Archicad or place it in Plotmaker. You can scale it in Plotmaker and as it is a vector image you can make it as large as you like.

I don't believe I have that option....is it in SAVE AS command? I going to go check. Be right back.

I DO have that option. Never scrolled down that before, of course I never needed to because I don't know what all those types of files are used for anyway.....
Thanks......really really apreciate the help.

I'm sure you could simply publish to PDF (with high dpi) to accomplish the same thing.

another method while in the hidden line view in the 3d window is to use the 2d (flat) marquee and copy to the clipboard. This is fast and easy and you can then paste it into a detail window (or wherever) and keep it with the project.

I'll try that one too. PS. the other 2dl method work great. Just what I was looking for. YU DA MAN!

I always liked this method since you can then add notes and have line weights in your drawing.
