    The best you can do is create many closely-spaced lights and adjust their illumination properties until you achieve a satisfactory result. You will have to compromise between rendering speed and appearance.

     

    AFAIK, this is the only answer. There is no easy, automated solution - you simply have to bite the bullet and do the work.

  2. I became tired of positioning loads of lights to simulate LED tape light strips, so I created this symbol: LED Tape Light.calibz

     

    The symbol is only 24" long - you need to use a row of several symbols to produce varying lengths. There are 96 lights per symbol at 5 lumens per light, for a total output of 240 lumens/foot. You can easily produce half the output (120 lumens/foot) by simply turning off every-other light. Adjusting the per-light lumen output is straight-forward but exceptionally tedious because the changes can't be made in the Adjust Lights dbx, you must modify each individual light (all 96 of them) within the symbol dbx. The symbols display reasonably well in both raytrace and physically based:

     

    Raytrace, 240 lumens (48 lights) / foot

  3. You can raise the large roof to provide a wall against which the small roof can terminate:

    Or you can slope both roof planes in the same direction and join them along the common edge:

    Or you could create a hipped intersection:

    There are other possibilities as well, but what you want is not doable.

  4. When I do pre-engineered steel buildings I don't worry about the steel shapes - only the column base locations and dimensions, and the general arrangement of the wall/roof layers (outset girts, inset girts, etc.). My building and wall sections use a lot of CAD. All other aspects of modeling the building are standard Chief techniques.

    Here is the work in progress.

    4 units takes 30 seconds to download.

     

    Loading is slow! I had to use Edge - the Viewer never seems to work for me in Chrome. Anyway, the elevations in your OP fooled me as much as they fooled Rod - I thought the area beneath the funky projection was a deck, but it's just a roof. I still think the best solution for the funky projection is wood frame, clad in TAFS, with a grey-colored TPO membrane for the top, flashed at the perimeter with a color-matched drip edge. GRP would give you more color choices, but maybe GRP isn't readily available in Florida. That said, looking at the model in 3D, I have to agree that Rod has a point - that funky projection seems like a lot of work for nothing. If it was sheltering a deck area it could be justified, but it's not even shading the roof-top a/c units!  I'm sure there are other considerations, but maybe you could eliminate the horizontal portion, along with the supports, and keep only the main vertical element that serves to break up the side facade. But, I suppose it's a personal choice - I believe form should have some kind of function.

    Personally I'd modify the wall below to extend right up to this feature, as shown in the attached image.

     

    It's a plaza deck! Why would you enclose it? The loss of a primary outdoor living/entertaining space is probably a non-starter for the client. Sure, there are challenges, but enclosing the space isn't the best answer.

  7. Alan, there has to be some kind of pitch to those flat portions, right? You're preferred method of 18" deep wood trusses could accomplish this easily. I don't see any substantial benefit to CFS over wood, unless the rest of the project is framed in CFS and the contractor doesn't want to mix materials/systems. I'd consider wood frame, excellent flashing details, and a fully-adhered TPO or gel-coat GRP membrane for the low-slope roof piece.

  8. Even easier:

     

    1. Draw a CAD profile and save it to your library:

    2. Draw an arc and convert it to a molding polyline, then add the profile:

    3. Position it within the cabinets:

    This method provides the lovely rounded edges on the curved piece.

  9. 1. Draw a truncated pyramid as so:

    This will be the curved counter piece.

     

    2. Draw a cylinder in the center of the pyramid. Make it taller than the pyramid. This will be subtracted from the pyramid:

    3. Boolean subtract the cylinder from the cone:

    pyramid5.thumb.PNG.72be638f8763f32a4e8d8422c4e04162.PNG

     

    4. Draw a box, larger than the pyramid, and do another boolean subtraction:

    pyramid6.thumb.PNG.f87ac7031a96f618116b8033bb15a00e.PNGpyramid7.thumb.PNG.1ceacbb8dc3a77a8fd7386f114fb27b0.PNG

     

    5.  In ortho view, grab the rotate handle and rotate the shape 180 degrees to the proper orientation:

    pyramid8.thumb.PNG.21b95867ae20b4c299ba4431c39be4b2.PNG

     

    6. Now position the shape relative to the counter:

    pyramid9.thumb.PNG.459dca3410136e417c7c1af8df5fff18.PNG

     

    What this technique can't give you are the rounded edges on the curved shape, so a better alternative would be to create the shape in another program, such as Sketchup. That said, someone else on the forum may have a better method.
