  1. Ha! brilliant. Thanks for that ? lovely thinking. I had been hoping they would've built in something for single-segment polys. Seems logical, because you can build wireframes in space with them that are handy for a bunch of things, shade-tree surveying, project envelopes, on and on. This function would realize the poly is a single segment, then tell you how long it is. They already know this (the information is there), I'd just like it exposed. Wouldn't that be cool? Probably a way to write a script for it...
  2. Is there any way easily to get the linear length of one leg of a 3D poly without using the dimension tool? I don't see it in the OIP... or anywhere else. Many thanks ?Michael
  3. I cannot snap a control point to a surface, either a planar extruded surface (the side of an extruded rectangle) or to a NURBS surface. I CAN snap NURBSpoints to edges, vertices, and to contours I generate, but that's it. Is this what you needed? re/ your "rant," it does seem to me the tech support folks at NV are not deeply familiar with 3D, especially NURBS yet. I don't see many users pushing the app like you do, so I'm not sure they get much call for it, though that will need to change now that more of us are working that way. There ought to be an option to leave the controls visible, and snapping to a surface is actually the reason NURBS surfaces were invented, I believe. Will Rhino do that? I've not worked with an app that will do it yet.
  4. Hi Kaare, THANK YOU! for that setting (Nearest Point on Edge). Don't know how I missed it. I had some tedious workarounds. .. ? I cannot snap to the control points of a surface or NURB Spline. The control points are visible to me only when I'm in 3D Reshape. I can snap the control points to existing objects (help objects), but not the other way 'round (can't snap existing objects to them, because I can't see them). v2008 is no longer loaded on my machine. Were the control points visible in 2008 when you weren't in 3D Reshape??
  5. Kaare, I do seem to be able to snap degree-1 NURBS to control points now. Not at any point on a curve, but on the midpoint and control points. Does that work for you?
  6. Kaare, A question for you (unfortunately not an answer to your problem above): If I want to snap one NURBS to another in 3D, it seems possible only at certain points along the curve. This is not the case in other apps (Shark, for example). Is this the same for you? This also seems like an oversight, but it seems important. -- Also, I am not quite sure I understand your dilemma above; could you elaborate a little more. I know this kind of thing is sometimes hard to explain...
  7. Could we control the value of the gray used for graying-out layers in the Interactive Appearance Settings? Very nice if we could lighten the value sometimes or even change the color. Thanks.
  8. Okay, actually you can measure in 3D using the 3D poly tool; the length of the vector (and its angular relationship to the layer plane rotated on the Z axis) appear in the data bar. This should appear in the OIP when you draw any edge in 3D.
  9. Wouldn't it make sense to have an editable field in the OIP for length of a singe-segment 3D poly and NURBS (degree-1)? If we want to edit the line length, we could do it directly in the OIP. A single segment 3D poly or 1-degree NURBS has vector magnitude information in it that we should be able to edit. If you are drawing directly in 3D, this would be very, very handy.
  10. Hi Peter, Actually, I *am* kind of embarrassed by what I wrote. It ticked me off that there were these booby traps, and I had to take a few swings at it, but it's not as bad as I made it seem. It could be documented better I suppose. I duplicated the 2D poly layer and really heavied up my important index contours, and I was all right, so thanks for that. But truly, yeah, the TIN generator is one heck of a powerful tool. Especially if you have to shoot the site radially ? adding the smoothing points really helps a lot. My "adventures" notwithstanding, I'm saving days of work. Thanks for the understanding reply and the help ? very appreciated.
  11. As you are converting a diabolically complex contour map from 2D polygons to 3D contours... Why doesn't VW put the 3D contours on another layer or in another class as they are made?? That would make sense, I think. And why remove the color and line weights from the graphic you are converting? There are a lot of keys to the geometry you are converting in the colors and line weights which make it simple to orient yourself. Then VW takes them away and asks you where you are... There are work-arounds, but geez, they didn't make this easy. If you are interrupted in the process, supposedly you can resume by starting over on the red contour ha ha ha ha ha Very hard to find the red contour! And your original 2D contours are now all the same color and line thickness, they are overlaid by the new 3D geometry. So if you goof when you resume, and you don't have a couple virgin backups, you are cooked ? all your original geometry is doubled up, and you can't see where this has occurred. And if on completion you don't tell VW to delete your orignal 2D polys (because maybe you need them), they are left on the *same layer* as the new 3D contours ? very hard to separate well! -- If the newly generated 3D geometry could be put into a separate class, a redline class for instance (an option to do this?), or on a new layer, that would help.
  12. MichaelK ? yeah, I've got 3D Conversion res set Very High. Really, as Kevin McAllister mentions, there seem to be different rendering protocols for Design Layers and Sheet View. I think they got 'em backwards ? I'd rather see the "good stuff" in the Sheet Layer viewports. I did send this in to Tech. It just seems wrong, not a bug so much as a goof.
  13. The file I had a problem with (above) is buggered... looks like it didn't make it across the divide from 2009 to 2010. *However*, this thread made me drill more deeply into resolution issues. Something does appear to be wrong here ? or at least I am getting reproducible errors on this machine (see attached PDF and VWX): I generated the objects like this: - 26' circle - Offset & duplicate inside 6" - Trim above the centerline, as shown. - Select everything and Compose. - Extrude 24" - Modify / Rotate / Rotate Left 90? to erect it upright. - Set to perspective view and adjust with Translate View tool. - Render in Custom Renderworks (Sht-4 in attached PDF); options for curve detail Very High and in Hidden Line with Line Render Options / Smoothing Angle set to 0?. The rings behind the arch were made the same way, duplicated upward using Move by Points. The model renders nicely in the Design Layer. ** BUT when I make a viewport (Sht-1, Sht-2, and Sht-3), Custom RW and Final Quality RW both render an obviously faceted profile! You can treat this somewhat by making a Foreground Render with Hidden Line (see Sht-2), but it doesn't actually solve the problem. ** Why ought it render well in the Design Layer and badly in the viewport?
  14. Miguel, many many thanks.
  15. When I render in wireframe, arcs are fairly smooth. In hidden line, they are faceted (see attached). If I use hidden line as foreground rendering in a viewport, it looks terrible. It seems like I figured this out once before, but I'm stumped now. How do you get the facets out of a hidden line render? I have Custom Renderworks Options/Geometry set to Very High curve detail.
