With placement of a Helipad, here is the Properties dialog box:
There is no option to Deselect “Snap to Ground” which will allow placement of the Helipad on top of a building. Is there a way to get this to show in the “Properties” window or I am missing something? Is this not available in the World Hub?
I haven’t had to do this before, so I can’t offer any direct advice. But does Mamudesign’s video help any? Look around 13 minutes into the video. I haven’t seen it all the way through. (I’ve seen many of his videos – thanks, Federico! – but not this one.)
Thank you, @N316TS. I have looked at Federico’s video and found, just as in another video I had reviewed, that the Properties window does not show the “Snap to Ground” property. I have to assume, unfortunately, that the World Hub does not permit deselecting this property.
I have looked at a few of Federico’s videos before and have always found them very helpful! I also have three of his packages installed in my Community folder. He does a great job and is a very positive and valuable asset to the MSFS Community!
Sorry to hear that! Looking at the documentation for the regular SDK (not World Hub):
https://docs.flightsimulator.com/html/Developer_Mode/Scenery_Editor/Objects/Helipad_Objects.htm
I don’t see a “snap to ground” option, even outside the World Hub. I only watched the video for a few seconds, but it sounds like that object you need to add is unavailable in the World Hub SDK, so maybe that’s something for Feedback ?
Interesting. I wonder if the Properties window changed at some point in SDK development? Federico’'s video and one other I viewed clearly shows a Properties window with many more properties and options shown, including “snap to ground”. I tried just changing the altitude of the helipad and it moves the edit box for the helipad but not the image itself. I’ll have to investigate further.
Thanks for pointing me back to the documentation!
Do you remember where in the video you saw the “snap to ground” checkbox?
This is a snippet from Federico’s video at 12:42. I don’t see a “snap to ground” property there:
This is the limitation I think we’re hitting in the World Hub version…at 12:42, he’s adding an object called CollisionRoad from fs-base:
which we can’t add.
That CollisionRoad has a “Snap to ground” property, but it’s a moot point because we can’t add it:
At around 13:47 in the video, he adds the helipad and it snaps to the CollisionRoad object.
@N316TS, thank you! Apparently, I saw the CollisionRoad property and thought that is what I saw in the other video, so I moved on. I had seen you needed a collision object but had not associated that with the necessary deselect of “Snap to Ground”. You’ve explained what is happening quite well! I will mark this as the solution because it explains things, although we’ve definitely found a limitation of the World Hub (at least for now).
Thank you! That 
Solution definitely belongs to Federico!
