Can Renderworks Create Quality 2D Linework in 3D White Box Model at the same time?

Recommended Posts

I have a project where we are unfolding the 3D model for presentation purposes. We have a complex 2d polyline "image" that is meant to appear on top of the 3D objects. I have the linework complete as 2D polylines of that image. The problem is the 2D polylines are not appearing in a non open GL white box 3D rendering of the 3d objects, even though it is on a plane above the objects in "real space."  Working view... it looks correct. Rendered view the lines are not visible. Any ideas if/how I can get quality 2D linework to show on top of nice 3D rendered white box geometry/in a non-open GL high resolution image? Can these two ideas be rendered to quality and peacefully co-exist in a 3D render? Any help would be appreciated... Thanks!

Easiest and most direct method:

1)Create a viewport of the whitebox rendering on a sheet layer, with the options and quality you want.
2) Create a second viewport from the same angle in Hidden Line, or Wireframe, whichever gives you the appearance you want for your 2D geometry. This viewport should probably have every class OTHER than the classes with the 2d geometry you want disabled.

3) Set the second viewport to have no fill.
4) Align the line viewport over the rendered one, giving you the line appearance you want as well as the rendered background.

This way, any time you make changes you can just update both viewports, not forcing you to recreate a composite each time you make a change.

You can make a viewport of the view that you want on a sheet layer. In the Viewport settings via the OIP - set the Background render to the white model render mode that you want and then the Foreground render to Hidden line?  See attached.  Or am I not understanding what you want?

Jim,

 

Its appreciated. I see the thought process at work there. I am playing with the steps now. Much more manageable, making sense and looking better. Thanks!

I should mention that the DPI of the sheet layer will affect the "width" of the lines (higher the DPI, thinner the line).  If you need thicker lines, try using an artistic renderworks option with a Pen setting that will let you control the pixel width.

When using artistic rendering with edges, you can set the edge to be 1,2,3,4,5...etc or even, .5, .3, 0.5, .05 and that makes thinner lines.

Great tip there on the thinner lines Luis! Did not know that.

Thanks all! This has been an interesting exploration. I am newer to this program I have been working with it on and off for about 2 years, I bought a full designer license this year. So I am fully on board, i.m.o. quite an amazing design and construction tool for sure. My goal for this questions was to get a high quality exportable image to use for presentation and printing purposes to a client of mine.

 

Jim, I attempted your overlapping viewports with different classes being active and having no fill etc.... And the interesting thing was it worked perfect until I attempted to export it as a pdf.

 

The fidelity for the pdfs was great as separated non overlapping viewports when I exported. The 3D rendered image in one VP and the 3D Linework in another VP rendered as hidden line rendering in the other... made perfect sense for a good work around.

 

But when I ended up overlapping the 3D linework VP over the 3D model VP the fidelity of the exported pdfs dropped considerably for 20+ MB/single pdf sheetlayer export to about 200kb, and the only thing that had changed was I overlapped the viewports on the sheet layer....

 

Perhaps I am not selecting a correct setting on the export as pdf setting but it seemed more like a bug or something with the conversion of two VP on top of each other being exported.. I am not sure.... I have no idea why the fidelity dropped and when I printed it out the crispness of the image and linework went to heck... 

 

Then I took the linework I had in the model and exported it direct to the actual sheet layer. Scaled it appropriately and applied it just like I was drawing on a top of the 3d image/rendering on an old sheet of mylar.

 

Then I exported that sheetlayer as pdf and still had the same fidelity issue..... if I move the linework off the top of the VP. The Fidelity returned to the PDF it was 20MB, overlap the linework ontop of the VP and it became a 200KB pdf. I have upped the Sheetlayer Resolution to 300 + DPI already. Anyways so in this it was only one viewport with polylines drawing on top... Needless to say very confused about the internal process going on in the PDF conversion...

 

So I figured what the heck I then decided to export the entire sheet view as an high quality image file, a png, and bang the fideilty and overlaps worked fine! Beautiful image...

 

 So do you think this is a pdf conversion issue I am running into... any thoughts about what may be occurring here all?

 

Anyways I am just making my way through and more deeply into the vectorworks world. I have 20 + years of experience in autocad, rhino, the adobe programs, revit, and design in general but this is the first program I have found that seems to integrate that entire workflow of design along with BIM and construction data coming along for the ridge. Its refreshing! And very impressive so far. Definitely not a beginners suite of tools. A Great Program for those that can think obtusely.... which is my bag for sure. Thanks for all the Tips. You will continue to hear from me for sure! Curious why with the viewport overlaps I could not get it to export a high fidelity pdf.... but I could with a png/jpg...

Is this for a single view? If you have the 2d linework and you have a 3d viewport rendered as you'd like could you just cut/paste the linework into the annotations space of the viewport?

kevin yes single view. Annotation space will probably solve the issue I was having with overlapping viewports and the pdf export issue... Thanks!

Also remember that sheets are control by resolution, 72 dpi is the default, good for 2d lines but for renderings crank it up to 300 or 600dpi, you'll be surprise with the quality, then export your pdfs. I do this type of process for my graphics team over here.
