Hello, you just need to calculate the center distance and make a rectangular network of components. If you only have 3 sleepers, place the middle one and then make the network.
In a room (single or multibody), you can go through a network and use your previous dimensions, by displaying the sketch or by using the "parametric" dimensions with FX. You don't have to calculate, Inventor does it for you, you select your dimensions and your signs (+-*/)
In an assembly, the network can retrieve a dimension or a network (of points for example) from a part or simply a network with a length /number of crossbeams.
For your information I avoid putting directly the result of a calculation, I let Inventor calculate for me especially when the dimensions already exist, which allows by going to parameter to change only a few dimensions or repetitive or regular use of the same part.
Indeed, I had managed to get out of it by calculating the center distance. A correct but tedious approach if you start to have a large number of pieces.
I therefore prefer to use a dimension in my calculation, which allows the centre distance to evolve according to the dimension. I was taught to draw like that, in a "robust" way.
Now I'm facing another beginner's problem, I don't know how to display (or retrieve) a dimension in the assembly. Apart from creating a sketch dedicated to displaying the rating? Where to display an FX setting?
Decidedly I can't do it. When you tell me "recover the existing networks and sketches, pass for modeling (instead of overview) you can then recover them".
I don't know how to retrieve them, they are neither selectable nor clickable, whether I am in overview or in modeling view. I can look in the aids etc... I'm blocking, any hint?
Thank you for your patience. But I think I'm getting lost among all this information.
I'm going to go back step by step to what I want to do, and if you can tell me where I'm making a mistake.
1. In an assembly I place a spar of a length L and a crossmember of a section S*S which I constrain to the beginning of the spar.
2. What I want to do: Distribute 5 crosspieces along the length L of the spar, making a network of components.
3. In my assembly ("assemble" tab), I click rectangular component network, I choose the component, the direction of the column and the number of columns (=5). Now I need to determine the spacing between the columns. I
4. I need to use the formula (L-S)/4 to calculate the center distance
If I enter this formula by hand, it works very well
5. But what I wish is to be able to retrieve L and S somewhere, either in a sketch or in the fx settings. and then I block
I am convinced that it is simple but that something escapes me.
I created a sketch in the assembly, in order to recover the dimensions I wanted. So in the fx settings, I can write them down (d5 d6 for example). When I make my network of components I write my formula with the d5 d6 . and that's it.
What even saddens me is that I am convinced that there is a way to get the d5 d6 by clicking somewhere (without having to write them down beforehand).
Thank you all for your contribution, it allowed me to research and discover several functions that I did not know.
