Sorry Kathryn - I'm just seeing this now. What Cheryl Lau‌ has provided is what you would do with your shape/polygon, but I think there is a way to apply her rule directly to your polyline. The polyline will import as a graph layer. From the inspector set your sidewalk widths to zero and then your streetWidth to the width you would like your polyline to be. From there you can apply Cheryl's rule to your "street". I had to use this type of solution working with some pavement markings once. Not at all what its intended for, but a clever work around nonetheless.

Perhaps a better/more immediate solution might be providing an option to create a group with the caveat that if you want to send messages and share materials with specific event attendees a group must and will be created. I would have to think that most events posted on the calendar are simply to drive attendance to those events and not necessarily create a "micro club" of event attendees. I would also add that for most public engagements and interest of transparency any information disseminated afterwards would be made accessible to everyone and not just those who attended a specific event.

Hey thanks Graham. All looks good on my end.

‎05-01-2019

Absolutely. Everything for our projects goes into a group, but even within that group, despite its settings, only the owner can edit the survey.

Thanks Brian. I appreciate the prompt reply. I like the concept of hiding groups and items.

I am constantly having to "Change Owner" of my survey items to allow my team to make edits to various surveys in Survey 123. I have even had to elevate the privilege of one of my employees to perform this function in the event I am not available. The only workaround I can see is creating a separate named user to manage/create/edit every survey. I think this functionality, or lack there of, is a shortcoming of Survey 123. Are there any plans to add this functionality.

I am surprised there is no way to roll back edits on ArcGIS Hub. This seems like a basic and necessary feature for any team based CMS. I am deathly afraid of letting any of my team members into my Hub site simply because if they make any unwanted changes or edits there is no way to undo or roll them back.

I've seen this in the documentation and I'm seeing this behavior and its leading to significant clutter in my organization's content: "When you create an event, a group is automatically added to your ArcGIS Online enterprise organization. It's important that you do not delete this group because it shows you who is attending your event." We are using hub for an initiative that will have 100+ events - and we were intending to use Hub for 30+ similar initiatives every year. In 3 years we will have 10,000 groups...that's simply not going to work. This seems very unnecessary simply to track who is coming to an event. Couldn't this be stored in data file in the Initiative's group?

Thanks Daniel. Please keep me posted. I have a client really putting the screws to me. I'm holding them off but I don't know how much longer I can wait before I have to move their solution to Wordpress.

I am assuming you mean a CityEngine Webscene. Honestly, 55mb is a little big. I have some detailed Webscenes that are way under this - 32mb - Downtown Battle Creek and 21mb - Downtown Oshkosh. You may want to look at optimizing - trees, cars, people, splits, etc... Can you share a link with me? In any event I have found that sometimes I have one or two shapes that create errors. If I'm using a parcel data set they are often this invisible slivers that are technically getting rules applied to them but they are so small I can't even see them. I would start debugging but selecting only areas of model and exporting those. By process of elimination you should be able to find a buggy shape, or a buggy model that's crashing your scene.

Wow you are really close. This solution is not well document. I used to have to refer to some other rules every time I was trying to figure this out. What you are looking for is the p function (probability function). Essentially you are testing a probability and will use it with a conditional rule. @Range(min=0, max=1, stepsize=0.1, restricted=true) @Percent attr PctA = 0.5 Generate --> case p(PctA): color(1,0,0) A else: color(1,1,0) B‍‍‍‍‍‍‍

Graham Hudgins‌ any update? Tech support has been non-responsive.

Okay I understand. You just need to work through the logic and the math. First split off the first parcel in one direction - I think z if we align our scope. Then divide up the rest by the even number with a split on the x-axis. If we are only doing 3 subdivisions then its easy, just divide in half. But if we are doing more than 3 we split in half and then split again for what is remaining (our EvenSplit). Hopefully you can follow the logic. @Range(3,5,7,9,11) attr NumSplits = 3 @Hidden attr EvenSplits = NumSplits - 1 Shape--> alignScopeToGeometry(yUp,1) SplitShapes SplitShapes--> case NumSplits == 3: splitArea(z) {geometry.area/NumSplits:NewShape | ~1: split(x){'0.5:NewShape | '0.5:NewShape}} else: splitArea(z) {geometry.area/NumSplits:NewShape | ~1: split(x){'0.5:splitArea(z){~geometry.area/EvenSplits*2:NewShape}* | '0.5:splitArea(z){~geometry.area/EvenSplits*2:NewShape}*}} NewShape--> print(geometry.area)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ and the console reports the areas to be just about exact Look good?

Unfortunately there aren't any libraries. There are some out of the box rules to generate buildings from footprints but they aren't of any specific vernacular. I think you'd be surprised with how quickly the rules could be written - but it also sounds like you need some research done. I'd be interested in helping out if you need it.

Do you mean control the number of splits of shape? Something like this would do it. @Range(0,100) attr NumSplits = 3 Shape--> split(x) {scope.sx/NumSplits:NewShape}*‍‍‍‍‍ You can also split by area. This code makes sure every subshape is the same size. @Range(0,100) attr NumSplits = 3 Shape--> splitArea(x) {geometry.area/NumSplits:NewShape}*‍‍‍‍‍ Make sense?
