Terrain generator not finding the remote server

Hi Ines,

I have just tried running "Terrain Generator" component in the analyse_terrain.gh file, and it ran without any problems. So at the moment the opentopography.org servers are working.

The screenshot you posted suggests, that "Terrain Generator" tried two times to download the terrain file from opentopography.org, and it failed to do that both times.

As the opentopography.org servers are working, the problem may be with your PC. It may for some reason blocking the "Terrain Generator" component from downloading the terrain file.

Can you please try these steps:

1) Close your Grasshopper and Rhino.
2) Restart your PC
3) When it boots up again, in your Start menu's search box type: "UAC", which will find your User Account Control Settings. Click on it, and a new window will open. Set the bar on the left to "Never notify".
4) Turn off your Windows Firewall.
5) Then turn off your custom Firewall (in case you have another one, besides standard Windows Firewall).
6) Then completely turn off your Antivirus.
7) Right-click on "Rhino 5" icon and then choose: "Run as administrator".
8) When Rhino boots up, run Grasshopper, and open the newest analyse_terrain.gh file from here. Do not increase the radius_ input. Try running it with the default radius: 600 meters.

After these steps, are there any warning messages with your "Terrain Generator" component?

Hey Djordje! That did work!! Thank you very much! 

However, I am still not able to make the "Terrain Analysis" component work. The TerrainGenerator creates a closed brep no matter what number I insert in the "type", I tried both 2 and 3 but it's still a closed brep. Any thoughts on this?

Hi Ines,

Glad it worked.

What does "a closed brep" mean? A brep which has a stand? This is what a stand is:

If this is so, then set the standThickness_ input of "Terrain Generator" component to "0".
Let us know if you are experiencing any other issues or questions.

Hi, Thank you so much for your speedy reply!

By changing that to 0 it is now a trimmed surface without a stand, yet the component still doesn't work, because it says that the data supplied is not a polysurface.

Here is a screenshot of the error I'm getting

Hi Ines,
Can you please internalize the data coming out from terrain output of "Terrain Generator" component, then save the analyse_terrain.gh file and attach it in here, or upload it somewhere and post the analyse_terrain.gh download link in here?

In order to internalize the data, use a new "Geometry" parameter, and connect the terrain output to it. Then right click on the "Geometry" parameter, and choose "Internalize data". Like so:

I just downloaded and ran your file, and it works without a problem:

Can you download and run the .gh file attached below, and then show what comes up from the readMe! output of the "Terrain Analysis" component? As a printscreen, the same way you did it last time.

Hi, here goes the printscreen! It still says it´s not a surface.

Hi Ines,
Thank you for running the file.
It says it's an untrimmed surface, which is basically a regular surface, so it is fine.
What's not fine is that it terrainObj should not be "None".

Can you please provide the following information:

a) which Rhino version, service release and which bit version
(in Rhino, choose Help -> About Rhinoceros)

b) which Grasshopper version
(look at the bottom right corner of your Grasshopper window)

c) which ghpython version
(open an empty ghpython component, or any Gismo component and look at its bottom right corner)

d) which Windows operating system and which bit version
(example: Windows 8.1, 64 bit)

Hi Djorje, here goes the information about the versions.

a) Rhino Version 5 SR7 64-bit

b) Grasshopper 0.9.0076

c) Ghpython plugin 0.6.0.3, Gismo 0.0.2

d) Windows 10 Home, 64 bit.

Thank you very much!

Hi Ines,

Gismo plugin requires minimum Rhino 5 SR9 (32 bit or 64 bit). So SR9 and everything above that: SR10 to SR13.
You have Rhino 5 SR7. I think this may be causing the problem you have.
When you uninstall the Rhino 5 SR7 and install a newer version (it does not have to be specifically SR9. The newer the better: SR12 or SR13 would be the best), I think your problem will go away.

Let us know if you have any further issues.

P.S.
The Ning forum which grasshopper3d.com uses, allows a user to reply to a specific post inside a topic. Whenever this happens the newly posted reply gets slightly indented below the one to which it responded to. However, this addition of new replies and their indentation needs to be limited as some point, as the width of the replies will eventually be equal to zero sort to say.
So when this limitation happens, you get only a "Message" link at the bottom of the reply to which you would like to respond to. The "Reply" is missing. To overcome this issue, just scroll slightly above, and once you find the first "Reply" link, click on it.
I hope this answer makes sense.

Hi Djorje,

That makes sense. I´ll download a newer version of Rhino and let you know!

Thank you very much!
