leader length and insulation symbol size

[Anonymous]

Hello

I am very new to autocad PLANT 3D and a have some problems.

1. The insulation symbol is a bit to big so it doesn't fit very well, is there a way to set the size?

    I've put the symbols by "ISO INFORMATION" on the 3D model.

    And where can I add the information for the insulation?

2. Also the leaders for the welds, parts, ... are a little bit to long, it creates chaos on the ISO.

3. Last question: the annotation is not very logical, he puts the overall length dimension under the other dimensions, is there a setting I overlooked?

If someone could help me I would be very happy 🙂

Thanks
