Why are you using a two-dimensional array with the first dimension size only 1? Is that only for the example?

Possible workaround: the parameters are dynamic arrays too. You can append items to it beyond its current size.

si = vardim2(a2)
if n > si then
	for i = si + 1 to n
		a2[1][i] = -1
	next i
	parameters a2 = a2
endif

Hi Kristian,

I only get this error when the array parameter is one-dimensional in the libpart editor. Change it two two-dimensional by inserting a column.

One and two-dimensional dynamic arrays are not interchangeable.

Thank you, Using BasicGeometricCalc macro is updated with clickable image links.

Hi John,

The vector is not the endpoint of the vector, just the vector itself. So in your case if (0.5, 0) and (0.5, 1) are two points on the line, the vector is (0, 1).

BasicGeometricCalc can return the unit vector between two points:

call "BasicGeometricCalc" parameters iFunction = 1,
                                      Point1X = toX,   Point1Y = toY,   Point1Z = toZ,
                                      Point2X = fromX, Point2Y = fromY, Point2Z = fromZ,
                  returned_parameters Vx, Vy, Vz, distance

Vx, Vy, Vz will be the unit vector, and distance will be the distance between Point1 and Point2.

Hi,

If you create the images in svg format, put them in a folder, LP_XMLConverter convertlibrary -excludesvg <folder> <tifffolder> converts them.
There is one limitation: it converts text with a default font, and gives a warning. Explode text in the svg editor.

Hi,

each input “direction vector” of BasicGeometricCalc has to be a unit vector (length = 1.0 meter). You get a unit vector by dividing each coordinate with the length.
The returned vectors are unit vectors too.

Hi Tim,

You can open it if you select the macro name, and press Ctrl-Shift-o. It is loaded with the add-on, not listed in the library manager.

Did you add gs_ui_current_page as integer parameter?

The 2d script doesn’t know about the variables in the UI script. You have to write the same request in the 2D script too, or move it to the master script (just don’t use the variables in the parameter script, as the request will be unsuccessful from parameter script).
UI_INFIELD can’t show variables. Is ProWidth and ProHeight a parameter? No matter what you assign to it in the scripts, UI_INFIELD will show the stored parameter values. You would need a PARAMETERS command to change them, but you can’t do it, as this request doesn’t work in parameter script.
You can show variables and current value of parameters with UI_OUTFIELD.

Then this should work. How do you check the return values?

Is that a parametric profile, or are you selecting different profile for myProfileIdx?
Parametric profiles don’t work with GDL, they always return their default geometry.

You need to write multiple subgroups for each target material.

When the status of SUBGROUP{3} is 0, the new cut surfaces will use the last MATERIAL, not the target.

I attached a screenshot of the “Profiled Rail” UI. The popup is an infield of a profile type parameter, in the red box you can see the size of the profile. This is done automatically by Archicad.
In the blue box there are two outfields based on variables returned by the request. The request itself can be in the UI or the master script.

Don’t think about the master script on its own, in fact it is prepended to the actual script that is run. So it doesn’t help with requests that can’t be used in a parameter script.
You can’t control the execution order of the scripts, generally parameter script is run before the 2D/3D.
Something like this:

master script -> param script: sets parameters
all variables cleared
master script again with the new parameters -> param script: sets other parameters
all variables cleared
master script again with the new parameters -> 2D script
all variables cleared
master script again with the same new parameters -> 3D script

If you have VALUES or PARAMETERS based on these in the parameter script, it is possible that the param script is run more than once, and the code you wrote will be executed more than once with different parameter values. Your condition B is based on A, but in the next run A is based on the last run of B.

You might need to use GLOB_MODPAR_NAME in the parameter script, based on which parameter the user changed, only one of the limiting conditions has to be applied.
