Is there a way to create a line on an iPad in MapBuilder?

    It should be possible. I'm not able to check on one at the moment, but you may need to load the page in landscape orientation in order to get the left bar to show up. From there, just select add new object -> add line, just like you would on a desktop.

    The mobile/tablet UI will hopefully get some improvements soon.

    Thanks for your response.
    I tried just as you said but could not get it to work.
    Not a big deal for me since the laptop works great.
    It would be convenient though when planning a trip from the coffee shop.
    Thanks, Mel

    I just tried this last night on an Android tablet and drawing lines and polygons just didn't work. I'm teaching about 40 people to use CalTopo next week and some informed me they don't have laptops--only tablets. Unfortunately they will not be able to use their devices and will instead need to pair up with those who have a laptop for the majority of the exercises.

    Please work on making the mobile experience as functional as the PC-based experience, which is fantastic.

    Can you describe how it didn't work? It looks like there was a recently-introduced bug that prevented you from saving new maps on mobile (and that dropped the first line you created), but I fixed that today, and even with that bug had no problem editing lines on an existing map on my android phone. I recognize that it's still clunky, but it's at least functional.

    I was trying to create a line on an Android tablet and when I would tap,
    the screen would just scroll around. Occasionally it would create a line
    segment, but I couldn't reselect the line, edit it or anything--hence I
    gave up. I have a better experience on my phone, but it's nowhere near the
    quality of the desktop version.

    I am able to create a line on my iPad. I’m now trying to get the line to snap to the trail. I have it in MapBuilder and the snapto box appears at the top and the trail hilites. But I cannot get snap to work. Am I doing something wrong? Thanks. Mel.

    I guess I need to temporarily disable it on mobile - I thought it was.

    It's not designed to work with a touch interface, yet, since capturing the user mousing over / off the line is an integral part of the way I implemented it, and there's no notion of mouse over / out with touchscreens. Hope to get that corrected at some point though.

    Please don’t disable the line creation on the iPad.

    I meant the snap-to feature specifically, since it doesn't work unless you have a standalone mouse hooked up.
