Subgroup operation performance

[jc4d]

Hello,

I have to create a "box" with control over the top most face angle, for it I'm using a SPRISM_ command. Now, the thing is I would need to have a thickness on the side faces and not having the top and bottom faces.

To get the result I'm going after,  I'm using a subgroup subtraction where I cut a box from the SPRISM_, not sure if this is the wisest way on solving this problem without affecting the performance or there is another solution.

GROUP "Out"
	GOSUB 10
ENDGROUP

GROUP "In"
	GOSUB 20
ENDGROUP


result_1 = SUBGROUP("In", "Out")


PLACEGROUP result_1
KILLGROUP "Out"
KILLGROUP "In"


END


10:
PRISM_	4,15,
	0.1,0.1,15,
	0.1,B-0.1,15,
	A-0.1,B-0.1,15,
	A-0.1,0.1,15
RETURN

20:
SPRISM_ mat ,mat, mat,
	4,
    0, B, 0, 0, 1, -15.0, !xb, yb, xe, ye, h, angle,
    0,0,15,
    0,B,15,
    A,B,15,
    A,0,15
RETURN

Hello @jc4d ,

SPRISM_ like other PRISMs  accepts holes directly in the command.

For example :

SPRISM_ 2, 2, 2,
		10, -1, -1, 1, -1, 1.5, 15,
		-1, -1, 15,
		1, -1, 15,
		1, 1, 15,
		-1, 1, 15,
		-1, -1, -1,    ! contour
		-0.8, -0.8, 15,
		0.8, -0.8, 15,
		0.8, 0.8, 15,
		-0.8, 0.8, 15,
		-0.8, -0.8, -1    ! hole

Would give this :

I think it's a more efficient than having to do solid operations.

Thank you @MetalFingerz . I'm glad to know that it is possible to create holes directly in the SPRISM_ as well.👍
