How to get the 3d position of a label?

[[Ma...]]

Good morning to all,

I have to get the position in the active 3d view of a label. With a dn label this is possible, but with a normal label it seems that it's not possible (the result is None). I am wrong with something?

If found the bug: if you just visualize the label, the offset posizion in 3d view is None, if you move the label the property "label_offset_in_3d_view" start to work. I attach a video about this that I think i't a bug.

Hi Marco,

Which version (incl. service-pack) of ZEISS INSPECT are you using?

Thank you and best regards,

Matthias

Anyone has an idea?

Sorry, I don't have this version available for testing any more.

With your gom versione don't you have this problem?

maybe try to select that element with the script?

Hi Marco,

I think this is a feature. The offset only exists, if the label was moved from its original 'standard' position.

Hi Nanno! My goal is to take the vector and the position in the 3dview of a dn label then create a normal deviation label in the same position of the dn label. Do you know the right way to do it?

hey marco, to clarify - you want a nominal surface point with dn check instead of a deviation label on the surface comparison? 

 

import gom
import numpy as np

gom_part = gom.app.project.parts[0]
label = gom.app.project.inspection['Surface comparison 2'].deviation_label['Surface comparison 2.1']
coord = np.array(label.data.coordinate)
normal = np.array(label.data.normal)

x,  y,  z  = coord.reshape(-1)
nx, ny, nz = normal.reshape(-1)

gom.script.cad.show_element_exclusively (elements=gom.ElementSelection ({'category': ['key', 'elements', 'part', gom_part, 'explorer_category', 'nominal_part']}))
##nominal surface pt
nominal_surface_pt = gom.script.primitive.create_surface_point (
	name_expression='Point_from_label', 
	point={'interpolated': True, 'normal': gom.Vec3d (nx, ny, nz), 'point': gom.Vec3d (x,y,z), 'target': gom_part})

##make sure its attached to cad surface
gom.script.cad.adapt_elements_to_cad (
	elements=[nominal_surface_pt], 
	normal_from_cad=True, 
	position_from_cad=True)

##mp
MCAD_ELEMENT=gom.script.inspection.measure_by_intersection_with_mesh (
	elements=[nominal_surface_pt])
#check	
MCAD_ELEMENT=gom.script.inspection.inspect_dimension (
	csys=gom.app.project.nominal_elements['system_global_coordinate_system'], 
	elements=[nominal_surface_pt], 
	nominal_value=0.0, 
	nominal_value_source='fixed_value', 
	type='normal')
