Hy all, i wish to know if there's any project to implement xml profiles/curve/sections file format.

Best regards, Mauro G

Is it a 'real' format? Which software opens it? Is there a description of it somewhere?

Yes, it's a standard in roads and tunnel plan and vertical axis and sections definitions.

here's and example:

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<LandXML xmlns="http://www.landxml.org/schema/LandXML-1.1" date="2016-08-24" time="10:07:02" version="1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.landxml.org/schema/LandXML-1.1 http://www.landxml.org/schema/LandXML-1 ... ML-1.1.xsd">

<Application manufacturer="Amberg Technologies AG" name="AmbergRail3" version="3.2.0.0"/>

<Project name=""/>

<Units>
<Metric angularUnit="radians" areaUnit="squareMeter" linearUnit="meter" pressureUnit="HPA" temperatureUnit="celsius" volumeUnit="cubicMeter"/>
</Units>

Hi all guys,

the question said by Mauro Graziani is very attractive; also I work in tunnels and do monitoring project profiles.
If possible enter the XML file inside CLOUDCOMPARE, would be great !!!!!

Thank's for your time Daniel, and best regards.

Then I guess it's interesting for some users (at least 2 ;).

I see that the format is LandXML (http://www.landxml.org/). This format is huge, but I guess we could restrict its usage to polylines only.

Of course we can add this to the TODO list. But as for a lot of items that remain in the TODO list for ages, the biggest issue is that it's hard to develop such things when we are not involved at all in the process and we don't use the format or any tool that can load it for instance. To speed up things you would need to find a developer with at least some motivation (or a friend, a colleague, etc.).

Thanks for ur time aniway.

Bye, u maded a great software.
