Lofting and placing cross sections

Anonymous
Not applicable

I am a newbie at Fusion 360 and I was hoping that someone help me.  I am trying to model the nose of an airplane.  I am having trouble figuring out how to place the scanned cross section of perpendicular planes along a line.  The line has crosssections at positions marked for frame one through five.  When I try to place the  image it comes out reversed.  I am also not sure how to position the image on the perpendicular planes.

 

In the file, the orientation box in the upper right has also lost the home button and I can't figure out why.

 

If I have done this right the link below should take you to the file.

Have you seen this video about lofting? I think it might be helpful in terms of how you organize sketches, and how you can control them parametrically.

I have done something similar to what you are attempting, with a boat hull and canvases. I’m not sure if being reversed matters in this instance, but if you want to flip the canvas you can do so in the Edit Canvas option you get when right clicking the canvas in the browser.  

 

Calibrate the canvas (RMB on canvas in browser) to fit your desired dimensions, you should only need to import one canvas.  Using only one ensures alignment consistency between sketches. Canvases can only be a guide, sketches are what you will use to create geometry.

 

I would place constriction planes at your cross section points, and create a sketch at each one. Viewing head on it should make it easy to draw sketch curves to match the cross sections- the canvas will be visible.  Draw one side and mirror (you will ned to sketch a center line), using the fewest number of spline control points possible. Those curves can be the basis for your loft. 

 

Let us know if this is not the kind of information you were looking for.  

 

I have sometimes seen the home icon disappear, restarting Fusion seems to bring it back.
