Is it possible to load defined shapes as layers?

in GM Script Language
1) I'm uncertain if defining a shape through a call of attributes is legal;
2) regardless, is it possible to load defined shapes as layers?

Going about this following my nose, I got this:

    Your method of entering the coordinates for DEFINE_SHAPE will not work because the command can not accept variable names for coordinate values (bug #24919 has been opened to address this).

    Bug 24919 has been implemented in the latest Global Mapper 19 daily build, and will be in the next Global Mapper 20 beta release (it was not in the initial download.)  Both the DEFINE_SHAPE and DEFINE_TEXT_FILE commands will now properly process variable references.

    Or is another approach to be considered?

    Hello,

    Your method of entering the coordinates for DEFINE_SHAPE will not work because the command can not accept variable names for coordinate values (bug #24919 has been opened to address this).

    These defined shapes can not be loaded as layers, however, and the Global Mapper scripting language does not have a command for creating a layer and features from coordinate input.

    Thank you for your reply, Bob.

    What is that command you referred to?

    I also had started to wonder if defining a text file from variables, exporting it, and then importing it was an approach to consider; however, am unsure if that's the best/ simplest way. I'm looking to learn as much as you're willing to teach :)

    Actually, using the DEFINE_TEXT_FILE command would be the only way to create layers. At the moment, however, that command does not handle variables as it should, so that will need to be fixed before your plan will work.

    Well, thanks anyway. I appreciate your reply.

    I've already done all of this in a spreadsheet, but was hoping to get a more elegant solution scripted. Maybe some other time.

    Is DEFINE_TEXT_FILE now able to handle variables as it should with v20 (b090518)?
  • kbelliskbellis Global Mapper User Posts: 514Trusted User
    Woohoo! Will test after meetings today in Bangor. Thanks so much for this Bob!
  • kbelliskbellis Global Mapper User Posts: 514Trusted User
    Still testing v20 (b090518) (472); not sure if this issue is related:
    The DEFINE_TEXT_FILE command acted like it was working; however, the IMPORT_ASCII command acted like there wasn't anything to import. The log indicates that GMT1F6A.txt was (somehow) identified to load; however, no such file is located in the defined folder.

    What exactly is going on here and have I screwed up something?
