I think it’s a good idea to display the length of the border, in debug mode, and with few lines it’s possible to get this feature.
to do this, I modify the function " def draw_edges(" in the source code “measureit_geometry.py” to this:
def draw_edges(context, myobj, region, rv3d):
# Only meshes
if myobj.type != “MESH”:
return
scene = bpy.context.scene
rgba = scene.measureit_debug_edge_color
fsize = scene.measureit_debug_font
precision = scene.measureit_debug_precision
# --------------------
# edge Loop
#
# uses lambda for edge midpoint finder (midf) because edit mode
# edge vert coordinate is not stored in same places as in obj mode
# --------------------
_lenght = ''
if myobj.mode == 'EDIT':
bm = from_edit_mesh(myobj.data)
obedges = bm.edges
obverts = None # dummy value to avoid duplicating for loop
midf = lambda e, v: e.verts[0].co.lerp(e.verts[1].co, 0.5)
else:
obedges = myobj.data.edges
obverts = myobj.data.vertices
midf = lambda e, v: v[e.vertices[0]].co.lerp(v[e.vertices[1]].co, 0.5)
for e in obedges:
# Display only selected
if scene.measureit_debug_select is True:
if e.select is False:
continue
if myobj.mode == 'EDIT':
_lenght = (e.verts[0].co - e.verts[1].co).length
else:
_lenght = (e.vertices[0].co - e.vertices[1].co).length
_text = '{} ({})'.format(e.index, round(_lenght, precision))
a_mp = midf(e, obverts)
a_p1 = get_point(a_mp, myobj)
# converting to screen coordinates
txtpoint2d = get_2d_point(region, rv3d, a_p1)
# draw_text(myobj, txtpoint2d, str(e.index), rgba, fsize) # old code - only index
draw_text(myobj, txtpoint2d, _text, rgba, fsize)
return
