It allows you to create Voronoi diagrams in GC, with the use of a program called QHull that you need to install. Instructions can be found on <a href="http://www.cerver.org" rel="nofollow">http://www.cerver.org</a>, as well as an explanatory video of how it actually works.</p> <p> I tried to make it work but I was not able to, I think I have not installed QHull properly as it seems to be a bit tricky. However, the programmer told me that it should work better in the V8i. You can track the conversation in the BE forum for GC.</p> <p><a href="http://communities.bentley.com/forums/39544/ShowThread.aspx#39544" rel="nofollow">http://communities.bentley.com/forums/39544/ShowThread.aspx#39544</a></p> <p>Cheers! </p> http://forum.uforg.net/topic.php?id=43#post-95 Tue, 24 Feb 2009 12:37:23 +0000 luis tillan 95@http://forum.uforg.net/ <p>Hello Gustav, </p> <p>Could you please let me know the schedule for the workshops from the 25th to the 27th......</p> <p>best, </p> <p>Luis </p> http://forum.uforg.net/topic.php?id=42#post-93 Sun, 22 Feb 2009 03:40:26 +0000 andrea 93@http://forum.uforg.net/ <p>hi, does anyone know of a way of selecting only features with odd indexes?<br /> ie: I want to project a series of curves onto a surface. The curves come in pairs and their indexes are:<br /> -bsplinecurve[0][0] -bsplinecurve[1][0]<br /> -bsplinecurve[0][1] -bsplinecurve[1][1]<br /> -bsplinecurve[0][7] -bsplinecurve[1][7]<br /> -bsplinecurve[0][8] -bsplinecurve[1][8] and so on....for many curves<br /> I would like to project only those ending in [x][1] or [x][7]. Is there a way of writing this?<br /> [x][odd], or [x][i+1] or something along those lines? </p> http://forum.uforg.net/topic.php?id=40#post-90 Mon, 16 Feb 2009 16:35:51 +0000 greg 90@http://forum.uforg.net/ <p>I am attaching the final model I made for my abstract. Ii tried to clean up the recursion script as it was suggested by Tom on Saturday, but there was a problem. When I deleted the coordinate system, recursion was working,but it was also applying a coordinate system every time I changed the recursion depth, along with the circle that I originally wanted. With the first script that was not happening, but I do not understand why really.</p> <p>The reason this is a problem is because when I was trying to apply a point on the recursion circles and replicate it, it wouldn't work , because the coordinate system was part of the recursion feature as well.</p> <p>Thank you!</p> <p> </p> http://forum.uforg.net/topic.php?id=41#post-91 Mon, 16 Feb 2009 16:43:11 +0000 greg 91@http://forum.uforg.net/ <p>Hello again. </p> <p>this about the parametric masterplan.</p> <p>Any ideas how I can tell GC to run a sequence of moments/light studies on a given period of time, in order to get a reading of the average light study of the area???</p> <p>I am thinking either to use goal seeker code, or using excel spreadsheets. To be hinest, I am not sure it would work, but I would like to have help with either way if possible, as I have never worked with either.</p> <p>Thanks again!!!</p> <p> </p> http://forum.uforg.net/topic.php?id=39#post-88 Tue, 10 Feb 2009 15:09:28 +0000 greg 88@http://forum.uforg.net/ <p>Hello again!!!!</p> <p>I am trying to set up an accurate orientation lighting calculation system in GC.I have a few questions tho as I come accross certain difficulties.</p> <p>I project the points on the imported surface, which was a MS smartsurface promoted to a BSpline Surface, but the projection does not seem to work as expected. I am attaching the file, but I am afraid I can only send the attached surface via email because of the size, so if anyone wants to have it please let me know.</p> <p>Now, I am using the 3dmax daylight system, which gives me the azimuth and altitude values in numbers, where I translated them in a BySphericalCoordinatesCS. Is there a possibility of a string use where I can keep changing the values in 3dmax and are automatically updated in GC???</p> <p>By the way,when I promoted the surface, it changed proportion and became a lot smaller than the original one, and there where certain deformations in the surface. any ideas why that happened?</p> <p>Now lets say that for every individual point that is being projected on the surface, i want a line connecting those points. I tried to do that but it seems that all the sunpoints create a line to the few points that are actually projected.I only want a line where the case is for example......SunPoint[10][10] and ProjectedPoint [10][10] and not between SunPoint[10][10]ProjectedPoint [10][11] and so on...</p> <p>one last thing.I am thinking of using CS instead of points to imitate the sun. Then I would make a line by StartDirectionLength and where that line intersects the surface, create a point. I ll give it a go right now and see how it goes...</p> <p>Thank you very much!</p> <p> </p> http://forum.uforg.net/topic.php?id=38#post-82 Mon, 09 Feb 2009 22:08:45 +0000 Joao 82@http://forum.uforg.net/ <p>Here goes:<br /> Microstation + GC V8i</p> <p>Trying to import a surface from Rhino into GC and use it to populate with points,</p> <p>Opened .3dm file in MS and saved it as .dgn<br /> ModelAttachment of .dgn file it's ok,<br /> Create 2 points and set the Range (seems) ok,<br /> bsplineSurface SelectElementsWithinRangeAndPromoteToFeature</p> <p>Surface doesn't show in GC and at the &quot;Symbolic Diagram&quot; showed as red, can't find anywhere a error message or something that explain what is going wrong.</p> <p>Any sharp pair of eyes - and mind - that can figure it out?</p> <p> </p> <p><strong>(surface.txt is actually surface.dgn rename file extension)</strong> </p> http://forum.uforg.net/topic.php?id=37#post-76 Wed, 04 Feb 2009 16:28:19 +0000 greg 76@http://forum.uforg.net/ <p>Hello everyone. </p> <p>I need a bit of help with something I try to make in GC.

The charged timing is also 'flexible'- probably as long as you are decent, patient and friendly!</p> <p>You can book a time slot on 020 7514 2147. The effective cut area is large at 1400 x 900mm. However, the machine has a max material cut somewhere around 2/3mm ply. In which case it takes a lot longer and costs a lot more! </p>
