Unit Issue When Using a Parameter Table

3D Design Volume Model
1

Hello

I have a mechanism modeled in CATIA and driven via a parameterization table.

In the Excel file converted into a parameterization table in CATIA, I entered values in mm.

Lengths (in CATIA options) are in mm.

When parameters are associated with my parameterization table, they are multiplied by a factor of 1000. So there is a problem of unity with meters and mm.

On the other hand, I would like to find a solution if possible without hacking (no multplication or division by 1000 here and there) so that the parameters associated with my parameterization table remain in mm and without taking a multiplier coefficient of 1000. 

Do you have any ideas on how to properly manage units when using a parameterization table?

Thank you in advance for your advice.

I think it is desirable to create these parameters in meter units

Hello, the syntax of the name of the Excel table parameters is good:

'mon_nom_de_parametre' (mm)

Edit I added the _ (I prefer)

Hi Franck,

Do I like you!! Intellectually, I specify of course.

I remembered that there was a specific syntax to properly manage the units in the parameterization tables but it was impossible to put my finger on it.

It's exactly what I was looking for.

Thank you and surely see you soon!

The simplest way for parameter tables is:

  1. To first create the user settings ("Settings" tabs) that you need.
  2. To associate the dimensions, constraints, etc of the model by formulas on the user parameters (it's duplicate but if you lose the table you can easily modify the model from the user parameters or recreate a new table.
  3. To create the table from the current model, choose vertical for the first collone (parameter names are often longer than their values).

That way we have the right syntax.
