"Locking" available dimensions to set points

JGoode
Enthusiast

Hello,

 

I am trying to lock a point to only be set to specific points. Usually I would just use Step in a Values line to define it but the points aren't evenly spaced throughout it all. 

 

Here is the script I currently have but I'm having some issues with it and I don't know where I'm going wrong:

(brick_position holds each possible dimension that the opening_point_2 variable should be able to be set to. 

I would adjust the opening_point_2 variable using a hotspot in 2D plan. )

 

base_point = 0
j=1
DIM brick_position[]
for i=1 to num_bricks
	brick_position[j] = base_point	! start of brick
	j = j+1
	base_point = base_point + (brick_w*0.25)
	brick_position[j] = base_point ! quarter of brick
	j=j+1
	base_point = base_point + (brick_w*0.25)
	brick_position[j] = base_point ! half of brick
	j=j+1
	base_point = base_point + (brick_w*0.25)
	brick_position[j] = base_point ! three quarters of brick
	j=j+1
	base_point = base_point + (brick_w*0.25)
	brick_position[j] = base_point ! Full brick
	j=j+1
	base_point=base_point+mortar_joint+(brick_w*0.25) !Add mortar joint space
next i
parameters brick_position=brick_position

if (glob_modpar_name = "opening_point_2") then
	k=1
	repeat
		k=k+1
	until ((opening_point_2 >= brick_position[k]) and (opening_point_2 < brick_position[k+1])) or (k > vardim1(brick_position))

	opening_point_2 = brick_position[k]

	parameters counter=counter
	parameters opening_point_2=opening_point_2
	parameters k=k
endif

@JGoode Sorted & tested. I had missed a pair of brackets in the dQtrBricks calculation. Revised code attached taken from my Master Script. 

	!Declared Variables
	! dBrickTotal  : Set in Parameters with optional dynamic hotspot in 2D script 

	_dJoint = 0.01		!Mortar joint width
	_dBrickLen = 0.300	!Full brick length without mortar

	!Calculate length of uncut bricks
	_dIntBricks = int(dBrickTotal / (_dBrickLen + _dJoint)) * (_dBrickLen + _dJoint)
	
	!Calculate remaining brick length 
	_dFraBricks = dBrickTotal - _dIntBricks - _dJoint
	
	!Round cut brick to quarter brick length
	_dQtrBricks = round_int(_dFraBricks / (_dBrickLen * 0.25)) * _dBrickLen * 0.25 
	
	!Set length to full bricks + mortar + cut brick
	if _dQtrBricks < _dBrickLen * 0.25 then
		if dBrickTotal < _dIntBricks then
		   dBrickTotal = _dIntBricks - _dJoint
		else
			dBrickTotal = _dIntBricks
		endif
	else
		dBrickTotal = _dIntBricks + _dQtrBricks
	endif
	
	parameters dBrickTotal = dBrickTotal

I would be more inclined to set "opening_point_2" in the parameter script with maths rather than using a loop e.g.

opening_point_2 = int(opening_point_2 / brick_w * 0.25) * opening_point_2
parameters opening_point_2 = opening_point_2 

 Obviously you will need to fine tune using the parameter with the base offsets, but the value should round to the nearest quarter brick when stretching or manually entered.

You could consider ROUND_INT as an alternative.

Can't seem to edit replies anymore? First line corrected...

opening_point_2 = int(opening_point_2 / brick_w * 0.25) * brick_w * 0.25
parameters opening_point_2 = opening_point_2

This works apart from the fact it doesn't take into account the mortar_joint. Therefore it doesn't quite go up in quarters... it goes 0.25, 0.25, 0.25, 0.25, mortar joint space, 0.25, 0.25, 0.25, 0.25, mortar joint space etc. Which is the main reason I'm struggling with it. Your bit of code works perfectly if I didn't need to account for the gap

I haven't tested it but see if this works...

 

dJoint = 0.010 !Brick joint width (preset parameter?)

!Calculate length of uncut bricks
dIntBricks = int(opening_point_2 / (brick_w + dJoint)) * (brick_w + dJoint)

!Calculate remaining brick length 
dFraBricks = fra(opening_point_2 / (brick_w + dJoint)) - dJoint 

!Round cut brick to quarter brick length
dQtrBricks = int(dFraBricks / brick_w * 0.25) * brick_w * 0.25 

!Set length to full bricks + mortar + cut brick
if dQtrBricks < brick_w * 0.25 then
    opening_point_2 = dIntBricks
else
    opening_point_2 = dIntBricks + dJoint + dQtrBricks
endif

parameters opening_point_2 = opening_point_2

Thank you very much for taking the time to write this. Unfortunately it doesn't "jump" up in increments like I would like. I've attached an image, the red lines are the points that I would like the point to be locked to and then obviously to continue along the length of the object.

This is brilliant. Thank you very much! I never would have been able to figure this out.
