Define Deformable Part 1

[ChevyM]

Hello,

is it possible at step 3 (Expressions) to make a few Number ranges instead of one?
i tried using the options tool but i didnt really manage to get the same thing as Number ranges.
i want to have the same Expressions rules as Number ranges but instead of only between 3.1 adn 5.6 i also want them between 8.5 and 9.2
is this possible?

Best regards,

So you want to limit a SINGLE Expression to be either between 3.1 and 5.6 OR 8.5 and 9.2, correct?

To an Engineer, the glass is twice as big as it needs to be.

between 3.1 and 5.6 AND 8.5 and 9.2
so its not possible to have 6 or 7 in the same expressions
is this possible?

About the best that I can do is create a Deformable part with the range set from 3.1 to 9.2 but which will default to either 5.6 or 8.5 (whichever is closer) if the input value falls between 5.6 and 8.5. See attached example to see how I did it (basically using a long IF statement in 'Test_Part.prt' file).

John, a small doubt is 'Then' required in the expression line?

It's not clear exactly what it is that you're asking? Could you clarify?

The 'IF' statement is part of an Expression which is found in the original part file from which the Deformable Part is derived. INSIDE the Assembly file you select a value for the Deformable Part, between 3.1 and 9.2 and then the part updates.

and how can you only set up a minimum or maximum?

A 'Maximum' is not an issue if we're talking about non-negative values since you just set the range from 'Zero' to whatever your desired Maximum value is. For a 'Miniumum', can still set a value for the Minimum value, it's just that you have to provide something at the other end of the range of values as 'Infinite' is not an option.

IF(height=>7)then(height)else...

You're right, the 'THEN' is optional. I do it more out of habit since it helps me keep track of the 'IF - THEN - Else' logic, particularly on long, nested statements like was used in this example.
