Fusion 360 Draw Line Tangent to Circle
Transcript:
By the end of this video, you'll have a solid understanding of all five circle commands that are available in Fusion 360.
For this demo, I'll be using some sketches that I've gone ahead and set upwardly to reinforce how the circles work. You can download the demo file in the video description.
The circle tool is another unremarkably used sketch tool in any CAD program. To make things even more than efficient, Fusion 360 offers 5 unlike types of circles. Each 1 is created using dissimilar selections and each one includes dissimilar types of constraints.
If you go to the circle flyout menu located in the sketch dropdown list, you'll notice all v circle tools are located in that folder. The first selection, the " Center Diameter Circle (keyboard shortcut "C") Creates a circle using a center point and diameter. Select to define the heart signal so specify the diameter. More ," is one of the most normally used circumvolve tools, which is why the Fusion engineers accept given it the keyboard shortcut letter "C" equally in Charlie.
The concluding thing I desire to point Creates a sketch point. More out before I comprehend each circumvolve tool is that if you find yourself using other circle tools a lot, and then you tin assign your own custom keyboard shortcuts to them. I'll link to the custom keyboard shortcuts video downwards below in the video description.
Now, I'll go ahead double click on the sketch in the timeline The timeline lists operations performed on your design. Right-click operations in the timeline to make changes. Elevate operations to change the order they are calculated. More to edit the sketch…so I tin draw the circles with the demo geometry. I'll select The choice mode controls how objects are select when yous drag in the canvas. More the Center Diameter Circle in the marking carte by right-clicking, selecting sketch at the bottom and the center circle is in the upper lefthand corner.
The Middle Bore Circle requires two mouse clicks. The beginning mouse click sets the heart signal of the circle. I have this rectangle here with 4 equal sides. I'll set the center past clicking on the center point of the rectangle where these ii construction lines cross. Then, as I elevate out with my mouse y'all'll notice that I can either type out a dimension, followed by the enter key, or I tin can click at the corner point if I want the circumvolve to line (keyboard shortcut "Fifty") Creates lines and arcs. Select a get-go and endpoint to define a line segment. Click and drag the endpoint of a segment to define an arc. More than up with the exterior of the rectangle… or I can click at the midpoint of a line, where the circumvolve will snap tangent to the border of the rectangle. So I'll just go alee and click here to snap the circle tangent to the edge.
Like any sketch tool, the circle tool will remain active until you lot select another command or hit the escape key on your keyboard. You'll as well discover that y'all tin switch between each type of circumvolve past clicking on a different type in the sketch palette.
I'll switch to the get-go ane, the 2-point circle Creates a circle defined by two points. Specify two points on the diameter of the circumvolve. More . The 2-indicate circle besides requires two mouse clicks. I'll click on the top line to set the first point. And then, yous'll see every bit I move my mouse around, the circle is tied to that kickoff diameter point, unlike the center circle that is tied to the center point. This 2-point circle gives y'all a fleck more flexibility to snap into other sketch geometry. For at present, I'll just click the top left corner of the rectangle.
The next circle is the 3-betoken circumvolve Creates a circle defined past three points. Specify three points on the circumference of the circumvolve. The points define the size and the position of the circle. More , which I'll select in the sketch palette. The three-point circle allows you to create a circle by defining 3 points of the circle's circumference, or the outer edge.
The beginning two points are the diameter or width of the circumvolve, and the third betoken is the height of the circle. For this circle, I'll click on this inner corner for the first signal, and the reverse corner for the second betoken. Then, you'll meet as I elevate my mouse around the circle will stay snapped into the offset ii points and it will resize according to the location of the third point. I desire this circle to be contained inside this geometry and so I'll click the midpoint of the lesser line… which you'll observe added a tangent constraint.
Yous can as well access all 5 circles from the right-click sketch menu, within the circle flyout binder.
The side by side circle on the listing is the 2-tangent circle Creates a circumvolve tangent to 2 sketch lines. Select two lines then specify the radius of the circle. More than . This circle requires three mouse clicks. The first two clicks will be points or lines that you desire the circle to stay tangent ii. So, the tertiary bespeak will be the size of the circle. I'll select these inner ii lines… and yous'll discover the circumvolve stays tangent to these 2 lines…even if the circle is larger than the lines. After clicking to fix the size or the 3rd signal, you'll discover the tangent constraints were automatically created for the 2 tangent lines.
The final circle is the 3-tangent circle Creates a circumvolve tangent to three sketch lines. Select three lines that the circumvolve volition be tangent to. More . Now, this circle works merely as the 2-tangent circle with the obvious exception that you will be able to choose three tangent pieces of sketch geometry.
I'll click this top inner line… the bottom inner line… and I'll click this top horizontal line… and notice that the circumvolve is tangent to this lesser line here, even though it doesn't physically touch it… and it's gone ahead and added all three constraints for us.
In summary, even if yous observe yourself mainly using center circles, you'll find that all the circle types offer a different corporeality of flexibility and control. Which circle you utilise really comes downwardly to your specific needs. The best circle is always the circle that will relieve (keyboard shortcut CMD/CTRL+S) Saves the file that is currently open. More you time from having to manually add constraints.
