Drawing graphics in 3d scene over 180th meridian

MichaelDenholtz — Thu, 03 Oct 2019 22:18:48 GMT

I'm using the SketchViewModel to draw regions on a 3d scene. I'm not able to draw anything that crosses the 180th meridian. I've noticed the same issue with the pre-built Sketch widget. Is this a hard limitation of drawing graphics on a globe or is there some property I'm missing or workaround?

Thanks!

Unfortunately this is a bug in the API and we don't have a workaround at the moment. We have an issue open for it and we'll look into it. Sorry about the inconvenience.

I've noticed the measurement widget is able to draw lines over the 180th meridian, but I haven't been able to identify why that's the case. Is that behavior something that I can duplicate somehow when adding graphics to a graphics layer?

We've fixed the issue for the December release Michael. If you want to, you can already try it out with the latest build: Sketch over dateline example. Let us know if you find any issues in the feedback repo.

This seems to be working beautifully. I'm using esri-loader. What happens to 'next' when this version is released in December? Is there a good way to cleanly transition from next to the official release version?

Happy to hear that it works!

next is the current development build and it is meant to be used to try out new features and see that they work for your use case. For production ready apps only use the official release version. Once we release in december, next will be the development build reflecting the 4.15 release...

Hope this helps, let me know if you have any other questions.

Unfortunately the central meridian related graphics fixes are critical to features that absolutely have to be live in my application for a conference the week of December 9th. I work with oceanographic data with a focus on the pacific ocean, so not being able to operate around the central meridian is difficult. Is their any estimated date for the December release?

ArcGIS Online release is estimated for December 10th, but API official release (final version with patches, documentation site, plugins, typings and other resources) is December 19th.

Thanks for the information. I ask the following with full acknowledgement and understanding that 'next' is not considered stable and is intended for testing use only and NOT for production:

Will an esri-loader using version: 'next' fail at some point around release time? By fail I mean will the 'next' at any point resolve to a non-existent build or incomplete build?

Unfortunately we don't guarantee anything about the 'next' version. I would really not recommend using it in production or live demos. I spoke to my colleagues and I modified my previous answer as well, best is to use the cdn version after the official API release date. Until then we make patches and the API can still change.

For the conference, maybe you could record a video of how it will work and tell the users this will be available starting with December 19th? Sorry that I can't give you any better news...
