Component icon text - zooming issues

[BasilioPV]

Description

Is not possible to keep the text-to-icon proportion when zooming.

Steps to Reproduce

Put a text into a component icon and use it on a system. If you zoom in the component, the text has the proportions (regarding to the icon) as designed:

But when you zoom out, the text size increases and "..." replaces the text that fall outside the box:

Expected Behavior

It would be desirable that the text size increases and decreases in the same proportion of the icon, to have a homogeneous design at all zooms.

Hi,

I do not know if it is related with this issue, but it is worth mentioning that the name text fields of components have a behaviour different from other text fields. The names are shown completely in the diagram of the upper model, whereas other text fields may be hidden or even presented with ellipsis (eg. Dr... instead of Drug).

For example:

and reducing scale:

Other similar example: and:

In those previous examples the size of the text was selected as (Auto). However, when selecting a fixed size the behaviour does not improve.

Also, text fields move sometimes in a strange way when applying zoom. For example, this is a image of a component instanced on the diagram view of a model: when reducing zoom: and reducing more: (F and R fields are out of the box).

Thanks!

Can you provide a minimal model? It is hard to understand with just images.

[BasilioPV]

Please find this model:

model ii

equation

annotation(
  Icon(graphics = {Rectangle(origin = {0, 52}, extent = {{-96, 18}, {96, -18}}), Rectangle(origin = {0, -40}, extent = {{-96, 20}, {96, -20}}), Text(origin = {1, 51}, extent = {{-81, 13}, {81, -13}}, textString = "text"), Text(origin = {0, -42}, extent = {{-86, 14}, {86, -14}}, textString = "text", fontSize = 20)}));
end ii;

Zoom in and out the icon and even the automatic text does not respect the original proportions:

You have reason @adeas31. Excuse me I thought that perhaps it was not necessary in this case. You may use the following minimal model:

I have defined three components with typical problems of text related to zoom. The diagram view of example is a shown:

You see that the name of the three components is ok, and the same occurs with the remaining text,, excepting with the third component that has two text fields associated with String variables. These text fields have been defined with a fixed and equal size, but the result is very coarse.

When I reduce the size through a zoom out: Although the name of components keep fine, the remaining text are incomplete and some of them (F and R in first component) seem moving to the outside of rectangle.

Thank you for your effort!
