Ok, step by step, - is no problem,
But after your first sketch for Board, you extrude it symmetrically so that it extends below the plane. any reason for that?
Yes Sir, As much as possible you use the origin for symmetry,
you will see when the second and third layers are made, they are spaced thickness apart, and the thickness of the table is still symmetric,
Moving on to Rail - Sketch2. What is the red circle at the mid point of the rectangle? Is that your midpoint constraint? Yes it is Horizontally tied to the Model origin in the sketch
I notice you like using the sweep function. Is that a pretty normal function that most use and I should learn it!? Use the tool that does the job,
Probably only my attitude, I only draw one, and copy the rest for most of what I do, sweep gives the instant result, so that means one profile sketch, for the four pieces of timber we need later on (path sketch was already there to use.) In real life you would cut the rails from longer stock, same thing.
I'm confused on Rail - Sketch 3. I think what you're doing is making the miters, but what are you actually doing to make them?
Yep, cutting the mitres, one rail becomes four pieces, I have collected the eight purple points by Sketch > Project,
Joined lines to those points, and then extended the lines, so they join inside the table space. When you change table size, the mitres still work!
Used Split Body, select the rail, and the 90 degree line is the cutter,
Doing it this way, avoids a Fusion error, if you use one of those lines, Fusion will fail to split the body as it needs a two piece result, and cutting the first mitre like in real life doesn't work in Fusion. Using the 90 degree cutter avoids this error, and you get four pieces from two goes with the Command.
What if you just drew 4 small lines, I did,
1 in each miter corner is that going to result differently? Fusion provides an error as above for the first operation,
I dont see anything that tells me what this red circle is in each inside corner though. Top corners of the rail (8 of them) were Projected to the cutter sketch - as above - needed for the parameter changing capability required
Also, one of the lines is blue, one of them is black (on each side) Should all be black, but didn't chase why not,
Then you cut the bodies from board and put them into rail
Nope, the table boards are in a separate component to the original rail component, after cutting the rail to four pieces, they are converted to 4 components.
Then, I guess split allows you to split a body at a line or something, and you do that in the 4 corners, As above yep that's it
Next, are you just taking each body and creating a component from it? Yes
Why do you turn everything into a component? Like each layer you make its own component,
In real life you will have 7 pieces of the table to cut, and glue
In Fusion, Joints work with Components, not bodies,
2d Drawings need Components, (I don't use them)
Bill of Materials needs Components, (I don't use them)
Components are easy to work with, in Assembly mode.
The grounding action at the end, what does that provide you with? Components are free to move accidentally,
I used it to show you that the table is still locked solid to the model origin, make you aware that the command is there, and it can be used first when making the component - even if the Component is empty. Should be used on the known base section of every Assembly model.
And lastly, the rigid group at the end, I dont see that doing anything either.
Wrong, the Rigid group is the glue - stops the rails from being able to fall off the edge of the table, Rails were free to click and drag until this is done.
Might help...
