Default annotation text height in flat-to-screen annotations too small

Hello,

It is a good question..For that I would underline some points.

___If it about Flat To Screen annotation "unattahed" to the model geometry, these annotation have the text height defined in standard screen units and the default text height is set to 3.5 mm and then the annotations do not spin, pan, or zoom with the model. This is what you read in Help Center : http://support.ptc.com/help//creo/creo_pma/r6.0/usascii/index.html#page/model-based_definition/about_flat_to_screen_annotation_orient.html 

You need to set Text Heith at the moment you want insert the annotation.

___If it is about Flat To Screen annotation "attached" to model geometry, then refer to then use check box "Text Height in Model Units". Refer tot his article : https://www.ptc.com/en/support/article/cs366643 

About Toolkit or Creo Customization tools, I am not certified on this technical area.

Hi @jstothfang

here is about Creo Toolkit, you can use the function ProAnnotationTextstyleSet().

A code example is available with TestSetup.c in pt_examples.

Here is an example used on a dimension: https://www.ptc.com/en/support/article/cs325206

And similar solution but for a drawing note: https://www.ptc.com/en/support/article/cs360235

and finally some code to create a FTS note: https://www.ptc.com/en/support/article/cs80810 

Combining all those you'll be able to create a FTS note and set the text height at creation.

If your code still fails, you can file a case, attaching a (minimal) project and we will support you.
