How Auto placement of COG using relations, can be done?

[VinitKadamITT]

Using relations, I am trying to place coordinate system or point at Centre of gravity of the part. As I change the part dimensions, the COG changes & I want to move the placed co ordinate system or point automatically. I used relations

$D13 = mp_cg_x("","CS1","")

$D14 = mp_cg_y("","CS1","")

$D15 = mp_cg_z("","CS1","")

$D16 = mp_cg_x("","CS1","")

$D17 = mp_cg_y("","CS1","")

$D18 = mp_cg_z("","CS1","")

but nigher coordinate system nor point getting placed correctly at the center of gravity of the part.

Eventhough I have maintained congig .pro option "mass_property_calculate" as "automatic".

Find attached file "cog_p1.prt.5" for details & your reference trials.

Hi,

you can create requested csys during measuring. NOTE: I guess that this functionality is not available in any Creo license.

• on Analysis tab click Mass Properties command
• click left button with glasses icon to computer mass properties
• change Quick option to Feature in combobox above button with glasses icon
• in dialog box activate Feature tab
• in Datums section check the option to create csys
• click button with green check mark

Hi,

CG coordinates are related to default csys.

Use following relations:

$D13 = mp_cg_x("","CS0","")
$D14 = mp_cg_y("","CS0","")
$D15 = mp_cg_z("","CS0","")

$D16 = mp_cg_x("","CS0","")
$D17 = mp_cg_y("","CS0","")
$D18 = mp_cg_z("","CS0","")
