Unclear script of project2{4}

[Nader Belal]

Hi everyone,

I was investigating project2{4} using the downloadable example supplied by Graphisoft in this page.

So by simple editing of the original script

for i = 1 to iCutPlanes
	put cutElevation + (i-1) * sliceHeight
next i


for i = 0 to iCutPlanes
	put 1+32,				! method
		2,					! parts
		1,					! cutFillIndex
		1,					! cutFillFgPen
		1,					! cutFillBgPen
		0.0,				! cutFillOrigoX
		0.0,				! cutFillOrigoY
		0.0,				! cutFillDirection
		1,					! cutLinePen
		1,					! cutLineType
		1,					! projectedFillIndex
		1,					! projectedFillFgPen
		1,					! projectedFillBgPen
		0.0,				! projectedFillOrigoX
		0.0,				! projectedFillOrigoY
		0.0,				! projectedFillDirection
		1,					! projectedLinePen
		1					! projectedLineType
next i


project2{4} 3, 270,						
	0,					! useTransparency	
	0,					! statusParts		
	iCutPlanes,			! numCutplanes		
	get (nsp)

It will provide this result in the 2D view

But when I reedit the script in the following way

project2{4} 3, 270,						
	0,					! useTransparency	
	0,					! statusParts		
	1,			! numCutplanes		
	5000,

1+32,				! method
			2,					! parts
			1,					! cutFillIndex
			1,					! cutFillFgPen
			1,					! cutFillBgPen
			0.0,				! cutFillOrigoX
			0.0,				! cutFillOrigoY
			0.0,				! cutFillDirection
			1,					! cutLinePen
			1,					! cutLineType
			1,					! projectedFillIndex
			1,					! projectedFillFgPen
			1,					! projectedFillBgPen
			0.0,				! projectedFillOrigoX
			0.0,				! projectedFillOrigoY
			0.0,				! projectedFillDirection
			1,					! projectedLinePen
			1,					! projectedLineType

1+32,				! method
			2,					! parts
			1,					! cutFillIndex
			1,					! cutFillFgPen
			1,					! cutFillBgPen
			0.0,				! cutFillOrigoX
			0.0,				! cutFillOrigoY
			0.0,				! cutFillDirection
			1,					! cutLinePen
			1,					! cutLineType
			1,					! projectedFillIndex
			1,					! projectedFillFgPen
			1,					! projectedFillBgPen
			0.0,				! projectedFillOrigoX
			0.0,				! projectedFillOrigoY
			0.0,				! projectedFillDirection
			1,					! projectedLinePen
			1					! projectedLineType

It simply doesn't work, the 2D space is empty.

Can someone explain me how to make this work ??

[Nader Belal]

Ok, I have narrowed the problem to one parameter ...

Why do I need the to use parameter buffer for "cutElevation" Parameter ???

[Lingwisyer]

Works fine for me without using a buffer.

I tried out the example object and I cannot seem to get it to work either...

I have been toying around the values of the parameters, and here what I have found:

*PS: To make it simple lets just assume you work with only one cut surface

1- Method works fine only when you use the same for the cut and uncut parts. This doesn't apply for methods (16 -> 8192)

2- Parts can prove itself a little bit tricky but not that much.

3- The most difficult part is to get the right combination between Methods a Parts, as not all will be the one you need.

@Lingwisyer

Anyway I have took the script to an object that I´m working on, stripped it from "32" method. It worked.

The problem that I have now, that the object I´m working on have openings that can change in type, size or location, so in the wire frame mode to works perfectly but in the coloured mode, I just can't make it work

[Lingwisyer · Accepted solution]

Your cuts are through a vertical surface so the shading is covering up the lower cuts which does not happen with wireframe?

[Nader Belal]

Thanks

[Lingwisyer]

Could you include an "If glob_view_type = 2" statement near the start of your script that will set all of your openings to the same height when viewed in plan? In this way you can cut them all with a single cutplane. No need to worry about overlapping shadings either.

Thanks a lot,

I was going to write to you the same answer right now, before seeing your question.

Is GDL is enhancing our telepathic abilities ???
