Draw Multiple Circles Same Diameter Fusion 360

Step one: Creating the file

If you start Fusion 360, it volition automatically create an empty new design for you. Just if yous have already opened upwardly Fusion, y'all should create a new ane every bit shown here:

Pace 2: Structurizing the parameters

Once you created your new file, you tin can kickoff with structurizing the parameters, which is the virtually essential part of parametric modelling.

Think about the model you are going to create and define variables, that you want to modify afterwards without modeling from scratch again or fiddle with typhoon dimensions.

For our example, we are creating a standard mounting rail based on the following drawing:

Y'all peradventure desire a mounting rail that is 200mm long instead of the fatigued 100mm.

Then this value will definitely be one, that should be parametric. Noted. Continue like this for all the dimensions y'all may or may not desire to exist parametric.

Think logically about values, that may exist fixed (due to international standards etc.) and exclude them from your list. Effort to minimize the amount of paramters equally much as possible. The reason is simplicity. Think of a very big associates (due east.m. a CNC-mill) with thousands of parts. If you parametrize everything, you will have a list of thousands of parameters and maybe only 20 of them are really essential.

That being said, for our tutorial, we are anyway going to parametrize as much equally possible, considering the model is very elementary.

For the cartoon above I come up upwardly with the following values that shall exist parametric:

• "Length" of the rail (100mm in cartoon)
• "Total tiptop" (7,5mm)
• "Inner width" (25mm)
• "Outer width" (27mm)
• "Full width" (35mm)
• "Thickness" (1mm)
• "Fillet radius" (0,8mm)
• "Hole diameter" (iv,3mm)
• "Distance between holes" (42,5mm)
• "Distance to edge of runway" (vii,5mm)

Stride iii: Setting up the parameters

Permit's set upward the values now.

You can find the parameters option in the in the post-obit menu structure within the design tab:

Solid -> Alter -> Change Parameters

It is also very recommended to pin this carte du jour to the toolbar as well, so you have direct access to it someday. Do this past setting the tickbox as shown beneath:

If you now click on the "Alter Parameters" carte, a new window will open up:

There are 3 sections.

Favorites: Parameters that yous set up every bit a "preferred" value, will show up hither. We'll come to that in this tutorial.

User Parameters: Here are parameters that you - the user - will set up manually. So this is our principal option.

Model Parameters: Here are parameters that Fusion sets upward automatically afterward you've modeled something. If you create due east.g. a cube, the edge length will show up here.

You lot've probably noticed the little + icon next to "User Parameters". Click information technology to create a new parameter. Another window volition popular up, where you lot type in the values from our structurized list now similar this:

Salvage the parameter past clicking "OK".

Do this for every value of the list from pace iii. You can also type in a comment for yourself, which is pretty handy. Imagine having 17 "Length" parameters named Length1, Length2, Length3 and and so on - with a little detailed comment, information technology'll be clear for you.

We'll end up like this:

At present let'due south say that in the finish, after our model is finished, all nosotros want to change is the length of the track, because everything else will be static afterwards and won't exist changed anymore. Do this by clicking the "Star" icon next to "User Parameter" in the row where the parameter "Length" is located:

The favorized parameter will at present evidence upwards in the "Favorites" tab.

Collapse the "User Parameters" tab, and then everything looks cleaned upwards:

Finished footstep 3!

Step four: Sketching with parameters

One time you've setup all the parameters, you can showtime designing with them. The magic begins now.

Create a sketch on any airplane and draw a rectangle. Instead of typing in the numerical values like you lot'd commonly do, you just type in the parameters you've fix before past using the corresponding words:

Is this already an A-ha moment for you? For me, it was amazing using this function the first time :)

Best affair: yous can even use mathematical operators for the dimensions:

Equally yous can likewise see in the screenshot above, below the formula (TotalWidth-OuterWidth)/ii there is another textbox with "d17". Since we mixed upward ii values past subtracting ane from the other, we created a new "parameter". This 1 will show up in the "Model Parameters" tab of the parameters tabular array as a parameter named d17. But it won't bother us at all, this is just Fusions way of processing everything you model.

Finish the sketch once yous've drawn everything.

Footstep v: Designing with parameters

You've finished your sketch and want to motion to the next dimension at present.

Select all sketched planes:

Extrude (shortcut "Due east") the sketch by the value "Length" and hit OK:

Use "Fillet" on all the outer corners (qty. 4) with the value "FilletRadius":

The correct mode would be adding a new selection to the fillet pick earlier. You can access the fillet over the timeline at the bottom of Fusion. Double-click on the fillet yous've already created before:

And then click on the "+" symbol to add a new selection:

Now just select the other 4 "inner" edges by left-mouse-clicking (without any other buttons). For the fillet value, you type in the formula "Thickness - FilletRadius":

Now everything fits perfectly.

Y'all're probably asking yourself, why nosotros didn't use the same parameter for all 8 edges. Because if we would, information technology would wait like this:

The fillets wouldn't correctly correspond to each other.

Step half-dozen: Parametric drills

Terminal step is creating the holes of the rail.

Create a sketch on the inner meridian face up of the rail:

Choose the "Draw Line" option and go into structure mode by striking the "X" Button or use the icon on the right:

The construction mode allows us to draw freely on the model without affecting the object itself, like "helping-lines".

Describe a line from the bottom center of the track straight upwards with the value "DistanceToEdge":

Tip: you lot tin can navigate through the listed parameters with the arrow keys and then striking enter.

Tip: you can see that you're in the exact middle of the rail if you see the symmetric triangle (midpoint symbol) when hovering along the edge as seen higher up.

Repeat those steps for the other side every bit well, then you'll end upwards similar this:

It is also of import that this symbol is actualization after drawing the line correctly:

It stands for "Perpendicular Constraint" and means, that the origin of the fatigued line has a real relation to (the edge of) the object. This is important considering when irresolute values in the parameters table, the design needs a reference to know from where it should depict those lines again.

Concluding step is the center hole, I bet after following the tutorial, yous tin create it on your own. But here's how it's done.

Stay in the sketch mode or open it up over again via timeline and draw a constructed line from the bottom to the middle of the electric current rails. The formula is Length/2, because no thing how long the runway will be, the middle of information technology volition ever be half the length:

Create a indicate at the end of the fatigued line and finish the sketch by hit "Finish Sketch".

Everything should look like this right now:

At present click the "Hole" context bill of fare on top:

Select the 3 points past left-mouse-clicking:

Now on the right side at the pigsty popup card, prepare the drill point to "Flat" and the acme of the hole to "Thickness", so it would adjust to a thicker or thinner cloth:

Last stride is to set the diameter to "HoleDiameter":

And voila - that's it. A parametric DIN track.

Now endeavour changing the length by accessing the parameters bill of fare again:

Ready the value of "Length" to any value you need (example 200):

Perfectly working and everything placed correctly.

Stride 7: Troubleshooting

If a hole disappears when making the rail shorter/longer or even stays in identify and doesn't move with changing the parameters, it volition very likely exist due to missing constraints. Be sure to snap everything properly and check if the constraint is really at that place, same with the midpoint etc.

Step 8: Thanks

Thank yous for following the tutorial, I hope information technology was understandable and that it helped you understanding parametric designing as well every bit opening new horizons for you when it comes to your next project.

If you lot need aid or support, write me a message, I would exist pleased to get in contact with you.

Happy designing!
