Attached is a Prime 4 file that allows you to plot text in a graph, like:
Of course it runs in Prime Express...
Enjoy!

I don't know. Prerequisite is that you have access to the full functionality of Prime. I'm limited to Express...
The text plotting functions create matrices of many rows and two columns. I think that for 3D plotting you'd need 3 columns. Now it's easy to augment the matrix with another row. Suppose T is the output of a text plotting function then you could add the third column with:
T:= augment(T,update1(0,last(T),0)+z)
to position your text on the x-y plane at elevation z.
The other thing is that the T will contain NaN values. I don't know if the 3D plots will accept them.
Success!

P.S. The better way to create the z-coordinates may be:
Which will preserve the NaN values.

I do have a problem when joining multiple meshes, though. I can't work out why there's a dark banding where the NaNs live.
The MP7 variables hold 3D meshes. vector p holds the first 4 numbers in Tetsuro's 3D Plot argument list.

(I was playing around with Tetsuro's worksheet to allow a vector of meshes as an argument to the 3D Plot component. The function meshmerge takes such a vector and places NaNs between each mesh to create a single mesh. It works on vectors of both 3-column xyz coordinate lists and of xyz planes)
Thats what I see in P6 (exchanging the NaN's for the imaginary unit 1j did not help and yields the same plot)

Interesting. It would seem they project to some point on the backplane (they certainly don't project along the surface normals). I wonder why they're black and grade into the yellow surface? Neither the surface fill nor the line colour is black.
That's a nuisance and somewhat restricts the technique's usefulness. I wonder if they can put a patch in before Prime 8 gets released? And add colormaps? (I love rhetorical questions ... 😈)
Sadly, either because I'm going blind or it's not there, I can't see any mention of Plot component improvements on the Roadmap.

Here is something strange (sligthtly off-topic) which I found while (unsuccessfully) playing around.
Is it a new unknown "unit"? At least its labelled as such. 😉
In real Mathcad the result is simply NaN, as it should be IMHO.
OK, coming back to the topic (not the topic of the thread but that of the last discussions) I created this test sheet with a function returning NaN's in a specific region. The effect unfortunately is the same:
I noticed that while a move the region around with pressed left mouse button, the projection lines disappear:
The black shades which you see in P7 still are there and as soon as the left mouse button isn't pressed anymore, the projection lines magically reappear:
It looks like I was wrong and too hasty when I said that Prime would have the advantage over Mathcad to accept NaN's in the 3D plot 😞
The unit NaNi is not only unknown, it's also undefined:
Together with the double negation in the exponent of 10, this is a sign of serious trouble that should be reported to the officials!

@LucMeekes If you could share another 3D Plot Function Sheet , it's the best.
that can apply in construction Text in 3D Modeling as picture below or in general
now, n=0 to 99 you can 3D plot. If you want to change the ORIGIN to 1, you should change the program.
Thank u

in my sheet I set Origin =1 so I can't use her. Could you convert for me for Origin=1?
Thank u
