If so comment and will add next step with (operator-less) bmesh code to take the measurements. Test file to play around with to see if this approach suits your needs. With all the bones selected, and with use individual origins selected as a pivot point centre, can 'fatten up the whale' by a scale factor of 2 on each vertex group like so. Here is the result, the base whale with a bone for each vertex group. Pos = 1 / len(verts) * sum((v.co.yz for v in verts), Vector((0, 0)))ДЄrmmod = ob.modifiers.new(name='Armature', type='ARMATURE') If ob.vertex_groups.index in (g.group for g in v.groups): Vgrp = Д«py._apply(rotation=True, scale=True) Then adds an armature with a bone for each listed vertex group placed at those median points. The script below, sets the length of whale to an arbitrary 10 blender units, applies rotation and scale.ДЇinds the median point of each listed vertex group Part 1, cleaning the model and making the armature. Having looked into a few incarnations of your whale questions, I previously suggested using an armature. I hope you guys can help me out! I apologize if the code is a bit messy, I'm very new at coding, particularly for Blender.

However, I feel that there may be an easier way to loop through this/I'm still not sure of how to actually set the cursor to said location. I assume the code that needs to be inserted would look something like this: def vgrouporigin(vgroup): Print(whalesDims) #print out the list of whale areas and volumes WhalesDims = (area,volume) #add the area and volume to an array Print ('whale',w,'surface area = ',area, 'volume = ',volume) #print surface area and volume with each whale

Volume = bm.calc_volume() #volume of whaleДЄrea = ((sum(f.calc_area() for f in bm.faces))) Scale(v,sfac) #scale each vertex group based on the index in sfac that matches the vgrp indexД«m=bmesh.new() #needed to calculate volume and areaД«m.from_object(,) #needed to calculate volume and area Vgrpindex = #list of indices of vertices to set 3D cursor to (in pairs of 2, first two correspond to Face, second two to Reye, etc.)Дef scale(vgrp,sfac): #scale vertex group of name vgrp based on scaling factor of name sfacД«py._set(mode='EDIT') #set program in edit modeД«py._all(action='DESELECT') #deselect any previously selected vertex groupsД«py._group_set_active(group=vgrp) #set vertex group active based on name in vgrpД«py._group_select() #select active vertex groupД«py.(value=(sfac,sfac,sfac)) #resize vertex group by sfacД«py._set(mode='OBJECT') #set program in object modeД«py.(value=(1,totallength,1)) #resizes the length of the whale (only the y axis) based on an index in total length corresponding to the index in whaleДЇor v in vgrp: #I think that this is where my new code setting the cursor to a particular location should go Sfac = #list of all scaling factors for vertex group and whale Vgrp = ['Face','Reye','Rpostpec','Rantdslfin', 'Rpostpdslfin', 'Ranus', If you want to take a look at the problem as a whole the code is as follows (for the sake of ease this code is only representative of one iteration and the sfac and total length values are simplified numbers): obj = _object My output is incorrect and it looks as though things were not properly scaled in the x direction However if I take the same steps as above and instead of scaling using the keyboard command I use (value=(2,2,2)) Then if I scale that vertex group using the 's' keyboard command and scale by 2 (hit s and then 2) this is the output

I then select the whole vertex group and find the sum of the edges (the length of the vertex group) using the measureit addon (the sum is found on the right side of the image) I am setting the 3D cursor based on these vertices from one vertex group that will be scaled However, since I have to run multiple iterations of this I need to use python rather than scale it manually, however I haven't had much luck figuring out the best way to incorporate this into my code. I noticed that the output when scaling vertex groups by a particular scaling factor does not result in the desired size (in terms of sum of edges within the vertex groups) and realized this was because I had to set the 3D cursor to the center of the groups (since I used a mirror modifier the center of the vgroup is really in between two vertices that I will note in the below code). I currently have a script that scales total length and selects and scales vertex groups of a 'whale' mesh.
