  1. I can find no references to the terms 'FL', 'CL' & 'datum line'. Can someone clarify this? As a designer I often use nurbs surfaces and rounded edges. The seams of adjoining nurbs surfaces sometimes show up in hidden line & artistic rendering modes, but not always. Rounded edges are messy in hidden line and do not seem to follow any clear principle. Short of a perfect solution, it would be nice, if I could invoke a dialog in rendered viewports, where I could identify unwanted & missing lines, and get a corrected representation.
  2. It will not work - maybe in the next update this will be fixed. Make a symbol of the 2D representation. Then make a new symbol including the 2D symbol and the image prop. Put this in your symbol folder and use it like any normal symbol, but be sure to convert it to a group before rendering. This way you will keep the 2D representation in the correct location.
  3. =LENGTH(((SEL=TRUE))) in a worksheet seems to do it. Perhaps you should check this with another source before you trust this.
  4. ... But I still wish I could do the same without the 'offset duplicate' option checked.
  5. Thanks Damo - I have never used the 'offset duplicate' setting, so I didn't know this. Also thanks to Balemi for the neat trick.
  6. Illustrator has a very nice menu item which repeats the latest command. If I make a duplicate-offset (alt-click n' drag), I wish I could repeat that with a keyboard shortcut in VW.
  7. Also: I always use the same settings in artistic renderworks, but I cant make the into a default - or save them as a custom setting. As a result, I make the same movements and mouseclicks hundreds of times, which is frustrating.
  8. I wonder what you can produce with a CAD program, that requires the accuracy, you seek? I do a lot of material for proffesional printing and never leave the RGB universe. (With renderings the 'correct job' is a very floating definition)
  9. Works just as well without the point light. (Last post, I promise)
  10. Just made a starshaped one using Photoshops 'lens flare'. This is a neat trick. Thanks for stating the problem:-)
  11. Oops - sorry - I believe, I misunderstood your intention. But here is a thought: Make a gradient, circular transparency map (white in the perimeter, black in the center and an all white map of equal size. Create an image prop, and use the all white tas basis - and the transparency map as mask (greyscale pixels) Let all the options in the bottom of the dialogue be checked. Let the size of the imageprop be correspondent. with the glow of the ligtsource. Edit the prpo-texture and disable shadowcasting and -recieving. Put a point light in the center of the image prop with no shadowcasting and smooth distance falloff. Group them together - but do not make them into a symbol, and distribute them, so that the props do not cut into any walls. Actually this idea is new to me. I just tried it, and it is really cool.
  12. I have the same problem. I believe it is a well known issue, that will be taken care of.
  13. You can emulate this quite well by giving the LED lightsource a texture with white colour and 'constant' reflection - disable shadowcasting/recieving in the texture - and put a single lightsource within the shape. Make the LED into a symbol, so you can reuse it.
  14. If the version of that FormZ is pre 4.0, I have had no succes with importing IGES files into VW - if they contain anything other than polygon-based geometry. After that version I have not tried yet. From other sources, it often works - and sometimes not. If the objects of the file are nurbs based, it is really cool to get the excact information through IGES rather than a polygon mesh through DXF/DWG. If it does not contain nurbsbased objects - chose the DXF/DWG. I have tried the SAT format a couple of times, but never sussesfully imported anything through it. I wonder what it is good for.
  15. Wood textures are not always oriented the same way. Sometimes I want to change from one texture to another - only to find, that I have to change the mapping on several objects. It would be nice, if I could rotate the texture globally from within the texture ressource dialogue.
  16. I have stated my question poorly: Photoshop is primarily pixel-based. EPS is pixel- and vector based. If you are going to use the export in Photoshop, you only utilize half of the formats ability - and not necessarily the better half. Perhaps you are better off using a purely pixel-based format like Tiff or Jpeg?
  17. Why use EPS as export format, when you want to end up in Photoshop?
  18. If you have Adobe Acrobat (or Illustrator), you can save the PDF as an EPS - or a high resolution JPG. From Preview, also to some formats, though not the EPS. It's not perfect, but it's there.
  19. Imageprops in VW cast shadows and show up in reflections. Those are hard to get right i Photoshop. It would be very nice to have some kind of preview option for imageprops in VW in wireframe like the preview in the 'Attribute Mapping' tool.
  20. You can't. Iges is supposed to be standardized, but I have had different results importing from different sources. Also separating objects can sometimes be a problem after import. If you have other 3D programs than VW, maybe you can try one of them as a translator. If not ask the source to change settings and export again. When it works, it is quite wonderful compared to DXF/DWG.
  21. If you have Quicktime Pro, you can create an animation in the usual way, open the resulting movie in Quicktime and export it to a picture sequence. Then batch convert these in Photoshop or Grapic Converter and stitch them together. You will hardly save much in the way of filesize compared to exporting to the MOV-format with 256 colours, however.
  22. Quote: >If you can draw this perspective and ensure that all the buildings are set at their correct Geodetic heights within a week your hired. Sorry if I upset you. But am I wrong in assuming, that all these buildings are already there to be photographed - and that what you need to do is to document the impact of a new building in that context? If that is the case, the angle of the camara lens can be read from the camera. The volume and borders of the new building can be established with great precision - by drawing extension lines from the corners of paralel, rectangular surfaces, establishing vanishing points and horizon. Using these with objects of known height and location to establish the excact borders of the new building mass, and fit the 3D model into these borders. If these steps are followed, and the 3D model fits, it will be correctly represented. I can do this in less than a day, so can you. What am I not getting here?
  23. With all respect, it seems to me, that what you need is to educate the persons at the planning hearings - and perhaps yourself - in the principles of perspective. If you have not yet done them by hand, perhaps you should try that.. It is a surprisingly exact method. If you go to a meeting filled with uncertainty, it is not surprising, that they will question the material, you present. If you are confident and speak with authority, they will accept it.
  24. You probably do not have a nurbs surface, but a nurbs curve. Transform it into a surface. - Or what you have is a group of surfaces. Ungroup and add solids.
  25. Unless I am mistaken, VW 10 does not export to 2005 dwg, but version 11 does (With VW 10 you can export to 2002 dwg). Both 10 and 11 will run with OS 9.2, however. The best way to export is to apply classes consistently to all objects, so that you can use this criteria to separate objects in the output export. (Classes will then show up as layers in the recieving end). VW 8.5.1 was very stable, but so is 10.5.1 and 11.0.1, and you get so much more, so why sit on it?
