zone stamp anchor?

__archiben — Mon, 26 Sep 2022 20:58:23 GMT

can anyone tell me if there is a way of defining an anchor point for zone stamps?

i've modified a zone stamp to be scale sensitive, but it keeps jumping around. anchoring it along the top instead of the middle would sort things out . . . but i can't find a way of doing that in the script or the zone settings . . . am i missing something, or will this have to be done through working it all out long hand based on the returned text height calculations . . .

In order to help, I'll need to look at the script.....

Ben,
that depends on your code.
I could not find any specific globals for the zone tool so try SYMB_POS_X, SYMB_POS_Y globals if they are not affected by scale changing.
However, I would need to see your script to give you the final answer I suppose...

Ben.

I tried (and "have done") it before. The objects origin is depending of the dropping position of the stamp text. Its position to project zero is changing, if you move the position of the text or of the whole stamp by drag and drop. SYMB_POS_X / Y is a good hint. It could be possible to "store" the first position, before any moving of the text into a parameter of this object by a

IF NOT(positionX OR positionY) THEN PARAMETERS positionX=SYMB_POS_X, positionY=SYMB_POS_Y

command. Now you could move the text by a graphical hotspot depending of the scale. Text output would be always related to positionX / Y + hotspot-translations. If you move the text by the normal drag and drop, it would stay then.

BUT: This does not work. In parameter script context PARAMETERS command does work, but unfortunately SYMB_POS_X and SYMB_POS_Y are always 0. I have complained this more than once. Last time to GS a few moth ago in hope they will change this anytime. But so far I do not see any secure way to get scale dependent positioning of objects. I "solved" it by exclusive usage of graphical hotspots. No normal moving of the zone stamp text allowed. Needs discipline.

5 years later I have the same issue. I use Zone_Stamp_2 16 that allows you to make your zone stamp scale sensitive. Pretty cool except for the "jumping around" because there is no anchor.
Other solutions or other zone stamps that have an anchor?

OK. I found out that in my case I had to open the Zone_Stamp_16 2 and save it as a new zone stamp. The only thing I had to do was make the offset parameters visible in display. Example: click on the X under display by the parameter "change the offsetY_200". This makes this parameter visible in the zone stamp settings. now I can offset my zone stamps to be placed correct in the different scales.

If you are using version 25, then switch to zone labels instead of stamps.

You can add as many labels as you like, in any layer, at any scale.

You can even label zones in sections.

The zone stamp will have its origin where the user moved it. If you draw symmetrically to the origin, it will be anchored to the middle.

Text is drawn with "paper size" height, but its coordinates are in model space. For scale-independency, you need to transform to paper size.

Illustration:

text2 0,0, "O"

mul2 GLOB_SCALE / 1000, GLOB_SCALE / 1000    ! 1 m model is now 1 mm on paper scale-independently
add2 -5, -5                                  ! move origin of drawing
line2 0,0,10,10
line2 0,10,10,0
del 2
