Draw text with Python in 3d coordinate system

Question

I know that I can use the blf module to draw 2d text, but is there a method to draw text at certain positions in 3d space?

I want to add a text right to a specific point in 3d.

Do you mean on the 2D projection of a 3D location, as in, for example, the MeasureIt addon, or in full perspective? Or.. in perspective, but always facing the viewpoint? — Robin Betts, Apr 23 '19 at 07:49
@RobinBetts can set blf.rotation(..) (and aspect) to rotate text on screen. I remember fiddling with this and accidentally rotated all the GUI text too. (oops meant to comment under answer comment) — batFINGER, Apr 25 '19 at 11:48

Thx, I found an example in the MeasureIt addon and here is some code from my Fast Carve addon to draw 2d text:

rv3d = self._view_context.region_3d
region = self._view_context.region
pos_text = location_3d_to_region_2d(region, rv3d, self._center)

blf.position(2, pos_text[0], pos_text[1], 0)
blf.draw(2, "r: {0:.3f}".format(self._radius))

I was hoping you would ;) ... perhaps, if there's a short enough chunk of code to clue other readers in, you could paste it into your answer, to make it 'BSE complete' – Robin Betts Apr 25 '19 at 09:04

@RobinBetts: I added the Python snippet from my addon – Jayanam May 08 '19 at 05:09
Hi @Jayanam can you share full script because I have the same question – Seyed Morteza Kamali Sep 04 '20 at 04:50

This is a script that adds text at position x,y,z and the text says "my text"

import bpy
bpy.ops.object.text_add(location=(x,y,z))
ob=bpy.context.object
ob.data.body = "my text"
