blender text mesh transformation

Question

So I have the labels set using the answer here

How to add text in blender using python

import bpy

tech_list = ["TechA", "TechB", "TechC", "TechD"]
for tech in tech_list:
    bpy.data.curves.new(type="FONT", name=tech).body = tech
    label = bpy.data.objects.new(name=("label"+str(tech_list.index(tech))),\ 
                                 object_data=bpy.data.curves[tech])
    bpy.context.scene.collection.objects.link(label)

But there is no way I can get these objects rotated 90*, the bpy.ops.rotate only works in edit mode on meshes and the labels are curves, I tried to convert to meshes but I get into infinite loop of trial and failure.

Would you be able to point me in the right direction?

Answer 1

The easiest way seems to use object.rotation_euler for this.

Note that Python always sets rotation in Radians. To convert degrees to radians you can use

Math Module

import math
degrees = 90  # example
radians = math.radians(degrees)   
degrees = math.degrees(radians)  
print(radians, degrees)      # return: 1.5707963267948966 90.0 

Formula

degrees = 180  # example
pi = 3.141592653589793
radians = degrees * (pi / 180)
degrees = radians * (180 / pi)
print(radians, degrees)      # return: 3.141592653589793 180.0

Script

import bpy
degrees = 90
pi = 3.141592653589793
radians = degrees * (pi / 180)

tech_list = ["TechA", "TechB", "TechC", "TechD"]
for tech in tech_list:
    bpy.data.curves.new(type="FONT", name=tech).body = tech
    label = bpy.data.objects.new(name=("label" + str(tech_list.index(tech))) , object_data=bpy.data.curves[tech])
    bpy.context.scene.collection.objects.link(label)
    label.rotation_euler[0] = radians   # index 0 = Rotation X = +90°
