● All executed code is displayed in Info

Info location: Scripting → Info (bottom left of screen)

● When Python tool tips are enabled, the operation code is displayed in the panel part.

How to enable: Check Edit → preferences → Tooltips and Python Tooltips

● If you press [ctrl + C] with the cursor on the panel (button) in Blender, the Python code will be copied.

1. Mode switching

Object mode and edit mode ↓

#Set to Object Mode
bpy.ops.object.mode_set(mode='OBJECT')
#Set to Edit Mode
bpy.ops.object.mode_set(mode='EDIT')
#Set to Sculpt Mode
bpy.ops.object.mode_set(mode='SCULPT')
#Make it Vertex Paint
bpy.ops.object.mode_set(mode='VERTEX_PAINT')
#Set to Weight Mode
bpy.ops.object.mode_set(mode='WEIGHT_PAINT')
#Set to Texture Mode
bpy.ops.object.mode_set(mode='TEXTURE_PAINT')

2. Shader mode switching

Wireframe and render mode ↓

#Switch to WIREFRAME mode
bpy.context.space_data.shading.type = 'WIREFRAME'
#Set to SOLID mode
bpy.context.space_data.shading.type = 'SOLID'
#Set to MATERIAL mode
bpy.context.space_data.shading.type = 'MATERIAL'
#Set to RENDERED mode
bpy.context.space_data.shading.type = 'RENDERED'

3. Switching transparent mode

#Set to transparent mode
bpy.ops.view3d.toggle_xray()

4. MATCAPS settings

It becomes easier to see dents on the surface ↓

bpy.context.space_data.shading.type = 'SOLID'
bpy.context.space_data.shading.light = 'MATCAP'
#Choose the one you like
bpy.context.space_data.shading.studio_light = 'metal_carpaint.exr'

5. Adjust CAVITY

The structure becomes easier to see ↓

bpy.context.space_data.shading.show_cavity = True
bpy.context.space_data.shading.cavity_type = 'WORLD'
#ridge is a ridge
bpy.context.space_data.shading.cavity_ridge_factor = 1
#valley is a depression
bpy.context.space_data.shading.cavity_valley_factor = 1

6. Randomize the color of the object

bpy.context.space_data.shading.type = 'SOLID'
bpy.context.space_data.shading.color_type = 'RANDOM'

7. Focus on the object

bpy.ops.view3d.view_selected(use_all_regions = False)

8.3 Increase the operability of the D viewport

● Zoom to where the mouse is

PreferencesInput.use_zoom_to_mouse

● Allows you to zoom close to an object

PreferencesInput.use_mouse_depth_navigate

● Allows the field of view to rotate around the selected object

● Can also be used in edit mode

PreferencesInput.use_rotate_around_active

9. Allow only selected objects to be displayed

bpy.ops.view3d.localview()

10. Align the viewpoint to the selected surface

#TOP for the following types,BOTTOM,FRONT,BACK,RIGHT,Contains one of LEFT.
bpy.ops.view3d.view_axis(type = 'TOP',align_active = True)
