Getting a Z Value from a node point

Anonymous — Tue, 23 May 2023 13:02:05 GMT

is there anyway i cant get a Z value or Real Level Value from a node point say from a roof plane...

i wanna be able to click on different points on my roofs and be able to give the surveyor actual RL heights.

auto cad does it. surly archicad can??????

This is beginners stuff

Read "reference levels" in archicad help & use level dim tool

The level dimension tool with the gravity set to roof will give you the hieght to the top surface of the roof at any point (in plan).

The elevation dimension style will give you heights in elevation.

These will place a dimension which you will need to delete if you just want to question the height.

The tracker in elevation will give you feedback for height without having to place a dimention.

Also if you have the roof selected and the roof tool active you can CTRL-click on any node and you will be given the level for the top and bottom surface of the roof at that point.
Be careful though because if you alter the figures you will change the roof.
You can add new nodes at any point by temporarily cutting a hole in the roof, enquire the height and then delete the hole.

And don't forget the "Create roof level lines" command in the Design menu.
It won't allow you to find the height of a particular location but instead shows you location of a particular height on the top or bottom surface of a roof as a separate line.

Sorry I meant the co-ordinate palette.
Just read the "Y" position as you move the cursor around - this will give the height above project zero.

The tracker doesn't have a "Z" height in elevation (or am I missing someing?) and of course only activated when you want to draw or move something.

Rather than cutting and deleting holes to get heights at points within the roof (in Plan view), you can add a hotspot at the point you want the height and command-click (Mac) the hotspot with the Roof Tool selected (as Barry described) to get the Roof Elevations dialog box.

You don't need a to add a hotspot, just ctrl/cmd+click at the point you want with the roof selected.

Along the edges of the roof this is quite true.
I was thinking more in the centre of the roof plane hence the need for the hole.

But as Erika points out you can crtl/cmd+click any where insde the roof plane to get the height.
Except if it happens to be over a node or edge of another element (such as a wall or column) or along the edge of the roof.
Then you are back to adding a hole to get temporary nodes or adding extra node along the edge as David mentioned.
At least that is my experience.

in the 3D window, i got Z in the tracker to do what im after

The hotspot will work anywhere, inside or outside the roof area, not only at the edge. The advantage of a hotspot rather than just command-clicking is that you can accurately place the hotspot, while without it you cannot be sure exactly where in plan you are getting the height.

Cheers David, a great tip. How did you come by this little gem?

Ahh - hotspot in as with the hotspot tool
I just assumed you meant a node and was wondering how you could place a single node inside the roof plane - which is why I suggested cutting a temporary hole.

But hotspots work like a charm - thanks for the tip.
Interesting how a hotspot will work but clicking on the edge or node of another element doesn't.

I'm pretty sure its been there since version 4.0, when there were not so many features to learn.

That's because command-clicking on some elements' nodes (like a wall) will cut the wall (Trim to Roof), I think a carry over from the earlier versions.

Glad to have passed along a small tip.

Brilliant. Thanks, Erika. If I ever knew this, I sure don't remember it!

For many reasons that come to mind, this is all that is needed, since a Trace Reference will likely have elements with hotspots at the points that are of interest.

(I wish the dialog that appears upon ctrl/cmd-click was more user friendly - it does not make it clear at all that it is displaying a point elevation.)

Thanks!
