1st of all, I want to thank you for your help.
2nd I have found an easier way to do it (
partially in Adobe Illustrator, but you can choose the program that suits you best
)
1. Create the vector image in Adobe Illustrator at 100%, then save it (that will be your template).
2. Then save it again with a different name.
3. In the new file, and text must be exploded and converted to a shape.
4. Create a new layer that will contain all the vector elements in it as sub-layers (let's call it 100).
5. Drag a copy of the artboard.
6. Select and cut all elements in the new artboard.
7. Create a new layer (let's call it 150).
8. Select the new layer, and "Paste in place" so the the copied elements be inserted in the new layer with the same layer structure.
9. Scale elements by 150%, then select the artboard and scale it 150% (make sure that you select the same origin)
10. Repeat steps from 4 -5 until you get the 200 & 300% scale.
11. Save file as SVG.
12. Go to ArchiCAD folder.
13. run windows command prompt
14. Type LP_XMLConverter convertlibrary -excludesvg [svg file location] [tiff destination]*
*If the source and destination locations are the same, LP_XMLConverter will simply not work
PS:
a. I have observed that svg files only accepts 1 artboard only (don't take my word for it), but it you have converted the svg to multipage tif, and the size in of that icon in the UI is messed up, then move the artboard behind the elements with 100% scale
b. Transparency in svg may cause troubles, best/easiest way to deal with it, is to make a rectangular shape with the same size of the artboard with 0 (zero) fill, and 0 (zero) stroke width.
A good friend of mine have once told me that I´m so brute that I´m capable of creating a GDL script capable of creating GDLs.
