help with equations

[Loutenr1]

Hello, everyone! I am trying to learn the use of equations:finger:

but I have a little problem:frown:.
in a set, I must pilot the distance between two plates using for convenience the value of extrusion of a cylinder. therefore imposed the equation in this way:

"d1@bobina"="d1@extrusion-extrusion1@500.0.58.part"

d1@bobina is the length I have to fly, while the rest is the length of the extrusion of the part I use as a reference.

the problem is that the extrusion is 130mm, the equation gives me as a result 180mm

specific that to create d1@bobina I added a distance bond between the two plates and I renamed it d1@bobina.

advice? :redface:

specific also that d1@estrusione-estrusione1@500.0.58.part is a length that varies according to the configurations of the piece 500.0.58

I discovered something else in the meantime... also configuring the component within the axieme, which works without problems, the equation does not seem to read the updated quota given by the change of configuration, but remains fixed on the quota present in the last rescue of the :confused part:.

example:

I create the "pippo" part and make 2 configurations, 100 and 200mm. such a measure is the length of the pip (let's say an extrusion). select configuration 100 so you can view it on screen, then save the part.

now I open the "pluto" axieme and insert the pippo part in its 100 configuration. I create an equation that moves two plates to the distance d1 of the pip extrusion in the configuration inserted in the axieme, in this case 100mm.

Now the beautiful... If I change the pippo configuration in the 200, the equation does not change, I always return the 100mm result, anyway! to change the value of the equation I have to open the pippo part, double click on configuration 200, save and exit. traffic light on the axieme and the equation is updated to 200 :frown:

Where am I wrong?

I think you don't have to use the equations to make a speech like that.
a way can be you create a configuration of the axieme es 100 , create another one and call it 200 at this point go in configuration 200 on the pippo, dx button "component property" select configuration 200
and you are in place changing the 2 configurations you have the 2 possibilities, the 2 plates if they are properly bound follow the pippo value and adapt to the configuration you have.

an equation that bets on a quota will always give you only the value of the active configuration, so don't go out.
I hope I've been clear.

or you can use a layout sketch on which to anchor your components.

thanks for the answer in the meantime :wink:. I don't understand the last point though. even in the example you mention, the equation points to a quota (the extrusion of poplar) or not?
In fact I created the axieme 100, then I changed the configuration of all the components to save it as 200 and everything went fine except the two plates. despite at that time the active configuration of pippo was that of 200 :frown:.
but perhaps I misunderstood the example.. .

Thanks for the answer:biggrin:, but I have no idea what you're talking about... I never used the layouts:frown:

I'm sorry, but as I said, I don't use the equations because you buy your life.
Your plate didn't fit because maybe you have a distance bond, and clearly if you don't change the distance this doesn't move.
If you restrain the first plate on a cylinder face and the second plate on the second face of the cylinder, this will follow this, so if you change the extrusion size fits this.
If you want to try the equations start on one part and keep in mind that if you have to fly a quota of 2 configurations it must have 2 equations, and suspend once 1 and 1 time the other.
I wanted to give you an example but I use 2010 and you couldn't open the file.

I solved... turns out that the second plate always has the same distance from the end of the cylinder, regardless of the configuration

thanks anyway for the help:finger:
