Rotate Sketch Plane, Sketch Plane Origin

[thepirate1]

Hi there: I have a sketch on an origin plane. I just want to rotate it by 30 deg.

I tried to redefine sketch plane - you need a pre-constructed plane to select.  OK, I'll make a construction plane. ... Uh oh, it does not allow you to select the construction plane in the redefine command.  GRRRR.....

After searching on this as much as possible, the best I found was to select everything in the original sketch, then copy and past into a NEW sketch on the construction plane.  WEll, OK...

... So I do this, and the origin of the new sketch is basically RANDOM with respect to the origin of the design.  so, it's very difficult to move the mess of copied-and-pasted stuff onto the right place on the sketch.  Yuk. 

1) Is there some way of just rotating a sketch around an axis, or redefining a sketch plane to a construction plane? 

2) If not, is there some way to make the origin of a sketch on a construction plane coincident with the origin of the design? 

Thanks mucho,

Instead of copying the sketch items to another sketch, just copy and paste the sketch (the sketch should be closed.)  You can then move the sketch copy.  It will keep the original sketch's origin.

Dear etfrench: Thanks for that suggestion, but ... how do I do this exactly? 

I can select the sketch in the browser.  I can command-c, then command -v, but nothing happens. 

Thanks,

Right click on the sketch to bring up the context menu. Click on the Copy command.  Next right click on the Sketches folder and click on the Paste command.  Move dialog will appear and you can rotate about the origin as well as use any of the other move options.

Of course you can pick that construction plane to re-define the sketch!

However, you need to make sure that the construction plane is made before the sketch. You can pull it back in the timeline to before the sketch,

The above assumes that the construction plane does not reference other geometry either from the sketch or made after the sketch you want to re-defeine.

Also when copy/pasting sketch objects from one sketch into another, the point-to-point move option allows you to precisely locate these sketch objects in the new sketch.

The question for me is not how to do that, but why ?

Hello:  Thank you for your suggestions, but on my mac the context menu has absolutely no copy comand.  Is there something weird about the timeline here?

Thanks,

Hello Trippy: 

The application here is very widely useful, not just something special for me:  Let's imaging you want to put a number of forms symmetrically around an axis.  I want to define the bases of these forms in a sketch, place them at the various angles around the axis, and then extrude them.  So, if I could make a sketch, then copy it and place at at these various angular locations, that would be really useful.  

So, how would you do this? 

Thanks,

If you are going to copy a sketch, are you talking about a circular pattern of identical forms ?

Would you have a practical example  of such an application ?

Wow, that was fast service...

You asked!   I am designing a photometric system.  Light comes in to this thingamajig along the optic axis.  Putting dichroics along the axis allows me to reflect away a waveband, so a series of dichroics allows me to pick off several wavebands.  

In the plane through the optical axis, the reflection geometry is always the same, it just happens in planes through the optic axis at different rotations . I just angle the dichroic to aim it at the appropriate angle.

OK, I want three wavebands, so why not put three sensors placed on a circle at 60 degrees around this optic axis.  So now I draft the reflection geometry on a sketch ONCE, and then if I had my wish, I would copy that sketch and paste it onto three planes at 60 degrees to each other. 

Now to draw the sensors and dichroics I just extrude their outlines from the sketch. 

Makes sense? 

OK, now how would you do it?

1st you need to understand the difference between a component and a body in fusion 360

http://fusion360.autodesk.com/learning/learning.html?guid=GUID-E37B0456-A867-429F-BF69-6A4626DD31E7

Then you you need to follow Fusion 360's R.U.L.E #1.

Create a component for the sensor and make sure it's activated.

creste you sketch and extrude your body

create a circular component pattern witht the create -> pattern tool.

[etfrench]

As Trippy says, create the sensor and dichroic objects as components, then use Create|Pattern|Circular Pattern to create new components around an axis.

Alternate way would be to rotate a sketch:

Rotate and move Sketch

Did this feature get removed? I do not see an option to Copy or Paste a sketch when right-clicking it in the browser.

"just right click and select copy."  

http://prntscr.com/pyo7v6  you can't!!

[etfrench]

Yes, you can.  You just need to know how😀

p.s. The secret is you need to be in Direct Modeling mode.

its don't work!

My its works 😮  What exactly is your its???
