Here’s the C# code that implements the new helper functions and two commands that use them: LLFP and PFLL (for LatLongFromPoint and PointFromLatLong, respectively). Let’s start with a quick Screencast of the code in action: In fact in tomorrow’s post we’re going to see just that: how we can retrieve information about the current coordinate system (in our case we’re going to focus on the name, but the code will be easy to adapt to get other information). The translation is based on the currently used coordinate system, which you can also via the GeoLocation object. in which direction to do the translation). The translation itself is extremely easy to perform: it’s a simple matter of choosing which of two methods to call (i.e. We’ll create a simple utility function to check the existence of a geo-location object and another to do the actual translation.
The capability is there – assuming a drawing has been geo-located – and is very straightforward to use. In this post that’s just what we’re going to take a look at: using the GeoLocation object attached to a drawing to translate between drawing points and lat-long values (and vice-versa). What I’d like to see in your blog is something that would show me how to get to the lat\long values of the location I have picked and convert them to the coordinate system that I have selected instead of having the user have to stipulate the location in AutoCAD. This functionality is something that we will use a great deal and I will definitely be writing some code to utilize it. Saw your post a while ago on the geolocation in 2015. I received a question from Coralie Jacobi, recently, in response to this recent post:
