I have no ideas how PME do this and dig inside not the best option - ton of stuff going on under the hood. I can't find such examples across the internet - 100 500 tutorials for just PIE, but not PIE inside PIE.

When I try to put just menu it gives me menu like this. Not what I looking for.

class FRP_MT_PIE_Menu(bpy.types.Menu):

def draw(self, context):
layout = self.layout

sc_frp = context.scene.frp_props
an_a = sc_frp.frp_angle_a
an_b = sc_frp.frp_angle_b
to = sc_frp.frp_transform

#LT
pie.operator("fgt.frp_rotator", text="- 90", icon='LOOP_FORWARDS').R_Angle = -90.0
#RT
pie.operator("fgt.frp_rotator", text="90", icon='LOOP_BACK').R_Angle = 90.0
#TO
pie.operator("fgt.frp_rotator", text="180", icon='FILE_REFRESH').R_Angle = 180.0
#BO
#LTTO
pie.operator("fgt.frp_rotator", text='- ' + an_a, icon='LOOP_FORWARDS').R_Angle = -1 * float(an_a)
#RTTO
pie.operator("fgt.frp_rotator", text= an_a, icon='LOOP_BACK').R_Angle = float(an_a)
#LTBO
pie.operator("fgt.frp_rotator", text='- ' + an_b, icon='LOOP_FORWARDS').R_Angle = -1 * float(an_b)
#RTBO
pie.operator("fgt.frp_rotator", text= an_b, icon='LOOP_BACK').R_Angle = float(an_b)


Using some menu_pie or pie instead of just menu give error like this:

layout.menu_pie("FRP_MT_PIE_SMenu_TO", text="TO - " + to, icon='NONE')
TypeError: UILayout.menu_pie(): takes at most 0 arguments, got 3"


Any ideas guys how to make it work as on first GIF - PIE menu inside PIE menu?

• Thank you for reply ,but gives a big clue how to do this gives, maybe, for you. I have read this API doc page already... and it gives 0 clues for me how to make PIE inside PIE. I really don't understand how it have to look to work as I want. I'm not some coder CODER man, just some copy/paste coder, beginer if you want. If you can help - show please some example, please, or write some explanation. If I knew how and what I wouldn't ask here for help. May 18, 2021 at 14:43
• Apologies. IIRC this has changed and could previously add a pie menu to a pie menu (at least thought you could, on testing see that it expands as a regular menu as shown (using pie.menu) Added an answer of how to do this with bpy.ops.wm.call_menu_pie May 18, 2021 at 14:51

Example using the Text Editor > Templates > Python > UI Menu Pie  template.

Calls itself if clicked on and expands as another pie menu.

Note. Does not auto expand as a pie menu.

import bpy

# spawn an edit mode selection pie (run while object is in edit mode to get a valid output)

# label is displayed at the center of the pie menu.
bl_label = "Select Mode"

def draw(self, context):
layout = self.layout

# operator_enum will just spread all available options
# for the type enum of the operator on the pie
pie.operator_enum("mesh.select_mode", "type")

# this one expands as a regular menu

# this one when pressed expands as a pie menu (of self)
op.name = 'VIEW3D_MT_PIE_template'

def register():
bpy.utils.register_class(VIEW3D_MT_PIE_template)

def unregister():
bpy.utils.unregister_class(VIEW3D_MT_PIE_template)

if __name__ == "__main__":
register()


• In my case pie.operator("wm.call_menu_pie", text="TO - " + to, icon='NONE').name = 'FRP_MT_PIE_SMenu_TO'. Thank you kindly, I hope this topic would help others like me (already spent hours to guess how to make it...) May 18, 2021 at 15:09
