  1. i guess this is a good lesson in doing things right the first time... i'll try a work around- namely creating a new layer with the correct attributes and then moving the objects to that one. then deleting the old one... thanks for the replies.
  2. i'm running into an issue with several drawing files. after creating a variety of classes and then modeling an item, whenever i try to go back and change the class style (for the fill or line weight for example) it hangs the program up indefinitely. is this normal, or am i missing something (or both)? thanks. g4 ibook, 800mhz, 640mb ram, vw11.5, os 10.4

    Help with RW...

    hi all- thanks for the advice. still can't figure it out though... i tried final rw and the bump had been only set to .1. same results- opengl looks great, rw is grainy seems to be almost b&w (i.e., no grays). looks like i'll be trying cheetah...

    Help with RW...

    thanks both for the replies... i've actually tinkered with a wide variety of lights as well as the scaling and mapping but still haven't had any success. i assume since the scale and map look great in opengl, they should appear good in rw. correct? and by the way i have ram envy with both of you...

    Help with RW...

    forgot... using vw11.5, osx 10.4 ibook g4
  6. i just purchased a dvd of some really great concrete textures- i opened the .png files in photoshop, reduced their size and saved as .jpg files. i mapped 'diffuse' to 'color', 'specular' to 'reflectivity' and 'bump' to 'bump'. rendered a simple model using opengl and it looks great (besides the lighting which i've yet to get right). the problem is i discovered that opengl does not cast shadows. so i decided to render with 'rw with shadows'. suddenly the image renders as a grainy black mess rather than the great textured opengl version... any guesses/suggestions?
  7. nicholas, do you think it's a matter of vw12 vs. 11.5? i will look at the model again, but i'm having a difficult time getting much information by ungrouping etc. (just my inability to learn that way i think). thanks also for the rendering tips... i will do some experimenting. is it possible to export a specific view such as those into a illustration program so that the lines are editable objects? also, to follow up on a previous question (and somewhat unrelated), what is the utility of loft surfaces? it doesn't appear that they are solids and so cannot be joined. thanks again.
  8. hi mike, i had seen that tub awhile back but never really explored it. i will make a point to do so and see what i can learn.. would you know if there is any information on the rendering technique? it's very expressive without being too literal.
  9. so i've had a chance to try out mike's method and i have mixed results (possible my fault). lofting between two ellipses for the side and two for the bottom works fine, and fillets without problem. the problem is when i try to model the exterior as an extruded ellipse and then 'subtract' the inner lofted shape from the outer ellipse- the program performs the action, but when i render it as a test i can see that it did not create a hollowed out sink/basin- all that appears is the solid outside extruded ellipse. i tried playing around with extracting curves and faces to combine solids but didn't have any luck. what's also strange is that for the final shape, the top rim (which is 1/2" wide) also needs to have two 1/4" fillets- not realizing that the 'subtract solids' hadn't worked i was continuing along to the end of the model- when i filleted the inner top edge, it seemed to fillet fine. when i went to fillet the outer top edge the out ellipse shape suddenly disappeared (i got the same results repeatedly).
  10. mike- thanks for the effort in helping. i will try this and see if i can duplicate your success. when you said you couldn't shell it, is this a technique i should be using? i have been creating the inside solid and then subtracting that solid from an outside one. wouldn't shelling the inside shape only create a uniform thickness? also, is lofting a problematic method when working in 3d? thanks.
  11. mike, i am (or was) an architect as well. i've always liked the idea of vw all in one package- but i also don't want to run into many modeling limitations. i realize i am working on fairly simple geometry so it's probably not an issue. as for rendering... i may be trying to get as realistic renderings as possible, and i've read that artlantis is more up to the task than rw. is that your experience? is it possible to get photo realistic renderings out of rw?
  12. this seems like an interesting discussion indeed... and a more complicated task than i had imagined. the lofting between the ellipse segment and circle segment seemed to work for me, allowing me to fillet also, but the shape became unusable. i couldn't tell whether i was working with a single surface or multiple as every time i tried to 'add solid' or 'subtract solid' it would hang my machine up indefinitely. mike, i was trying to model the inner and outer shells seperately, but thought subtracting one from the other was the most efficient way to create the final shape. i'm not entirely sure how to go about extracting the connecting surfaces (do you mean the upper rim?), but i will give it a shot. i'm interested in any more comments as well and will fill in my own- a warped plane seems like a complicated geometry but i would think that's what these programs are for. on an off topic, what other modeling software do you have experience with that might work better? i've used form-z a little but actually mostly in 2d. i would think that a 3d modeling package is only as good as 1) it's ability to render or 2) it's ability to export shapes so they can be imported into another rendering program. that brings up limitations of the rendering program. for example. if this model is so difficult to create in vectorworks, how well would it export to artlantis?
  13. nicholas, thank you for the reply and i'm goint to apologize now for the long response: 1- my initial problem the sides of the sink basin were made by taper extruding an ellipse. the bottom was made by trimming a 2d ellipse into four equal parts by bisecting it each way with a line. i then converted these elements into nurbs, moved the end points of the lines (which would be at the center of the full ellipse) down the z-axis. i then used the loft tool to make a sloped plane. i mirrored this three times to recreate the full ellipse shape, and then added all the solids together and then added solids with the side. the problem was that the fillet effected only the edge only belonging to the side piece and left the bottom group of loft surfaces unfilleted. 2- progress i realized that lofting the quarter ellipse as i was created the same shape as a drastically taper extruded ellipse. so i recreated the bottom shape this way, added this solid to the sides and it seemed to fillet fine. 3- next problem technically, this shape does not represent the sink bottom. to be truly accurate i needed to make using the loft technique again. this time i drew and ellipse for the outside shape of the bottom and a circle at it's center for the drain. i then bisected it each way with lines and trimmed everything to a 1/4 quadrant again. i then lofted this surface- the difference is that it creates a warped plane rather than a tapered cone, which is technically correct as the edges of the bottom slope non-uniformly to the edge of the drain circle. i then took a 1/4 ellipse for the side and taper extruded it and joined this solid with my 1/4 warped plane bottom. after joining these the fillet worked fine. the problem is that if i try and join 4 of these to create the full bottom, or if i try to subtract any one of these solids from the outside shape of the sink, it locks my computer up. i left it spinning for 10 hours overnight. is any of that clear? my system: ibook g4800 mhz, 640mb ram, os10.4.4, vw11.5
  14. i've found a workaround for the above problem... creating a loft surface out of a quarter ellipse joining down to a quarter circle, i get one 'quadrant'. this seems to fillet perfectly. the only problem now is that after mirroring them to create the full ellipse shape, the program is taking a looong time to 'join solids' (it may not even complete as it's been churning for a half hour now). i tried converting to generic solids to see if that helps but no luck. any suggestion on how to achieve this without grinding to a halt? thanks.
  15. i'm modeling a fairly simple sink- completed it and the deleted it by mistake (don't ask). i now can't recreate it and need help. the inside walls are a tapered ellipse; the bottom is made from four loft sections. after joining all these solids, i need to fillet the bottom inside edge (which i figured out how previously or got lucky)- the problem is now when i do that, the fillet doesn't effect the bottom surface and i am left with an edge that sticks past the fillet. any help would be greatly appreciated... should i use the techniques posted for a elliptical cone rather than the loft surface? if there is a way to upload images here let me know and i will. thanks.
