Ah, @Campbell Barton (campbellbarton) changed that API yesterday or so, will check all of our add-ons in case others used that prop too…

Dimensions is now read only? That kinda sucks. I know I used and seen other addons use that. How are we suppose to size objects with python now?

Edit:

I found a way ,but it now uses 5 times as many lines of code, LOL.

import bpy

NEW_X_DIM = 30

ACT_OBJ = bpy.context.active_object

X_SCALE = NEW_X_DIM/ACT_OBJ.dimensions[0]

if X_SCALE != 1.0:
	bpy.ops.object.transform_apply(scale=True)
	ACT_OBJ.scale[0] = X_SCALE
else:
	ACT_OBJ.scale[0] = X_SCALE

I believe you can do that with that single line:

obj.scale.x *= new_dim_x/obj.dimensions.x

Looks like I need to read up on my python more. I never could get it to work without first getting my scale back to 1.0.

That’s more like transformation math or something… ;)

Anyway, after second thoughts, I really do not see why that was made read-only, for python API it's a handy shortcut, even if it may have not been working well for UI (only because of multi-editing, actually…). So will revert that part of rB1b8c3774a86ebc04fceb9cd.
