Getting model size for post processor

[erik.valtanen]

Hello,

I would like to know if you can somehow get the 3D-models dimensions used in a program to post prosessor. The "Block" parameter only seems to give you the extents of current toolpath and is not really giving accurate results in simulation and other things.

I tried searching through program classes, but there is nothing resembling "Model". Can it be done?

Thanks

You will need to use a macro to calculate the model limits and write the NC Program:

Real List Xmax = {}
Real List Xmin = {}
Real List Ymax = {}
Real List Ymin = {}
Real List Zmax = {}
Real List Zmin = {}
FOREACH $M IN FOLDER ("MODEL") {
	REAL ARRAY Lims[] = limits('model',$M.name)
	int a = add_last(Xmax, round($Lims[1],5))
	int b = add_last(Xmin, round($Lims[0],5))
	int c = add_last(Ymax, round($Lims[3],5))
	int d = add_last(Ymin, round($Lims[2],5))
	int e = add_last(Zmax, round($Lims[5],5))
	int f = add_last(Zmin, round($Lims[4],5))
}
Real Model_Max_X = max(Xmax)
Real Model_Min_X = min(Xmin)
Real Model_Max_Y = max(Ymax)
Real Model_Min_Y = min(Ymin)
Real Model_Max_Z = max(Zmax)
Real Model_Min_Z = min(Zmin)

KEEP NCPROGRAM ;

You will need to create 6 user parameters in your Postprocessor:

udp_Model_Max_X

udp_Model_Min_X

udp_Model_Max_Y

udp_Model_Min_Y

udp_Model_Max_Z

udp_Model_Min_Z

And add to the commands:
