Rossford Posted June 15, 2021 Share Posted June 15, 2021 Related to my overlapping site models, my client has asked for more slope categories than VW's standard 6 (7 if you count the "in excess of" category. They actually want about 12. My idea was to copy the reduced area site model and do one slope analysis from 0-5%, leaving the excess white, and the next model with various colors from 5%+. However, even with low opacity it doesn't work with the bottom layer colors dulled out. It occurs that if a white color could be given very low opacity in the color palate manager, maybe that would work? But, I don't see anything in the help guides that suggests such a nearly "no fill" color can be produced. Any other ideas? Quote Link to comment
Jeff Prince Posted June 15, 2021 Share Posted June 15, 2021 @Rossford I'm curious as to why they want that. Perhaps that will inspire an easier way to address the problem. Quote Link to comment
Rossford Posted June 15, 2021 Author Share Posted June 15, 2021 Jeff, I need to overlay slope analysis models to get the number of classifications I want. I figure if the lower slope model has the over 5% slope clear (I tried white) or very opaque white, I can put it over the other site model where the slope analysis will be from 5.1% up. I have tried one opaque site model over the other, but it doesn't work. I suppose I could trim the site model on top, leaving no color. Is there a way like Photoshop where we can remove color from an object? Thanks in advance. Quote Link to comment
Jeff Prince Posted June 15, 2021 Share Posted June 15, 2021 (edited) @Rossford So why does the client want it to have so many categories? Edited June 15, 2021 by jeff prince Quote Link to comment
Rossford Posted June 15, 2021 Author Share Posted June 15, 2021 These are golf green "heat maps." Their intent (although I have never, as a golfer, figured out just how the book tells me how hard to hit the putt!) is to help both golfers and also greenskeepers in putting the hole locations in an area golfers could be expected to reasonably make a putt, with anywhere from 3-4% being the absolute maximum, and 1.5% the minimum for drainage). So, then, the map needs to show <1.5%, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 3.75, 4, and then areas of steeper slopes (in some kind of deep, warm, red!) for slopes from >5%, >10, >15%, >20%, etc. With a little tweaking I might get them to accept fewer, but not only 7.

Jeff Prince Posted June 15, 2021 Share Posted June 15, 2021 @Rossford So you are trying to get something like this: https://www.strackaline.com I think it will be difficult to achieve that look within Vectorworks. Splitting your analysis across two models as you suggest and editing the outputs in Photoshop will likely be your best route. Quote Link to comment
Rossford Posted June 15, 2021 Author Share Posted June 15, 2021 Exactly, but for a competitor! Quote Link to comment
Jeff Prince Posted June 15, 2021 Share Posted June 15, 2021 @Rossford I think you might have better luck by commissioning someone to write you a custom plugin for displaying such fine information within Vectorworks. I've seen similar done in Rhino3D. Maybe someone has created slope analysis in Bryce3D. 1 Quote Link to comment
Jeff Prince Posted June 15, 2021 Share Posted June 15, 2021 @Rossford if you need a little inspiration, here's how to use grasshopper in Rhino to do slope analysis. Perhaps this could be achieved in Marionette. I just haven't looked into the functions available. Quote Link to comment
AlanW Posted June 16, 2021 Share Posted June 16, 2021 @RossfordHi, Not sure if this helps but can get the different slopes to show up as different colours in VWorks. Untitled1_v2020.vwx Quote Link to comment
Rossford Posted June 16, 2021 Author Share Posted June 16, 2021 Alan, Yes, that is what I am doing. I just need to convince the potential client that 7 variations is enough. We asked VW if it was possible to change those number of categories of slope, but apparently, that is pretty well buried in old code, and not easy to change. I will keep looking into Marionette and Data Viz, but obviously, the easiest is to just stay in VW basic functions, and perhaps convince them that 7 categories is enough! Quote Link to comment
AlanW Posted June 17, 2021 Share Posted June 17, 2021 @RossfordHi when i was playing around with marionette a few years ago i used this website to create my own marionette nodes, maybe there is one there that can help under the site section or others. you can convert the code to a marionette node. https://developer.vectorworks.net/index.php/VS:Function_Reference Quote Link to comment
Rossford Posted June 17, 2021 Author Share Posted June 17, 2021 Alan, thanks for that. A few of those resources look like they might have promise and I will look into those. Quote Link to comment
