Valve Scaling Issue

Hi all

 

I have seen similar threads for this but none seem to have work a-rounds that'll work for this case. I have generated symbol blocks for some valves and found that they preview rather large on insert and when inserted assume the correct size (10mm x 5mm as drawn).  If I set the symbol scale from 10 down to 1, the preview is the correct size but then when inserted the symbol scales down to 1mm x 0.5mm.

 

So following this example i left the scale factor at 10 and made due with the rather large preview.... BUT... now when I insert a control valve and choose the same valve body, it is inserted at a scale of 10 (100mm x 5mm).

 

How can I control the scaling between hand valves and control valves so that they insert correctly?

Kind Regards

Thank you for sending the project. So I could look for it and I see that the ball valve block, opened in the block editor via project configuration, has a length from left to right of 10 units. All other valves like check valves have only the length of 1. So scale this block to the length of 1 and this will solve the issue for you.

 

In summary do that:

  • Open project configuration of your project
  • Switch to the node 'P&ID DWG Settings - P&ID DWG Class Defintions - Engineering Items - Inline Assets - Hand Valves - Ball Valve
  • Click 'Edit Block'
  • Scale the block: Base point 0,0, scale factor 0.1
  • Save the block

There is something wrong in your project settings. I will send you a separate email with the access data for a FTP-site. Please, upload there the project.

I have an additional question regarding the scaling in P&ID.

 

As i started my recent project I used 2 different templates to create my drawings.

So I got 2 drawings created from 2 different templates. 

Now i created symbols and lines ect. When i draw them in drawing 1 i have the right scaling that i want but in drawing 2 it has another scaling. I didnt change the factos of the symbols it self but it seem as there are scaling factors in the background of each drawing. I never found an option to change it.

And it has nothing to do with the conversion of inches to cm, i already checked that.

 

does anyone have an idea?

 

Greetings _ have a nice weekend
