Thank you for your answer Barry - so it seens to be exact like I feared...
But... could it be possible, to add an level-marker-sign by using the ArchiCAD-API? 'Just' add an 'special' addon and then the 'select marker-sign-pop-up' offer the additional level-marker-sign in addition to the 'default'?
Is it possible to tune a tool-dialog using the API and creating a proper addon (*.apx)?
Background info - or: why this modification is important for me:
in Austria there exist an official standard (like ISO-Standard), how the marker-signs in a building-plan should look like. Although GS is informed about this standard and lots of complaining and begging happend (since AC_v7), the signs we need in Austria have not been added by GS.
This issue is not a dramatical problem - yes, we create a library-part as 'workaround' - but it is a shame. Although it is ridiculous in many nasty discussions, when the 'opposite' do not know what to say against ArchiCAD, come: "... but you even can not use the correct level-dimension-marker-sign... (hahaha) " - I hate it -because it's true
If it is possible to change this ridicoulous situation for ArchiCAD Users in Austria by using an *.apx and no changes in the workflow, no "dimension-library-parts" - they are like a fucking wooden-leg, it would be great.
Thanks to all members, who can help me giving infos about this issue to me - you help to "make this dream true"
Yours, catch17
