How to Stitch (or patch) these two surfaces together?

[JayWBeck]

I'm trying to learn how to stitch together two curved surfaces.  The curved surfaces are similar and the hole through them is perfectly aligned and the same size.  I'd like to add four vertical surfaces forming the sides of a hole joining the two surfaces.  Please see the image file.

For example, the first surface might be a plane created with points 1, 2, 3, 4.   In my case these 1, 2 are vertically aligned and so are 3,4.

I expected to be able to stitch by picking points but that doesn't work.  What I'm lacking is an understanding of the basic approach to surface construction via stitching or patching (I think).

Also, what is a screencast? How are they made?

You use Surface Patches to join surfaces together, then you stitch them all together to create a solid.  Attach you model and let the forum users show you how on your model. 

A Screencast is a video recording created by the Screencast application which is free from Autodesk.  Normally it is installed automatically with Fusion 360 but you can download it from here.

You can loft between the edges of the surfaces and than stitch the bodies to make a solid or, it looks like your surfaces are equally spaced apart so you could just thicken one of the surfaces to make a solid.

I created a couple of surfaces that resemble your model and did a Screencast to show how I add surfaces and then stitch it together to make a solid.  You also see an example of a Screencast recording.

Thanks for your screencast solution to my problem.  I learned so much from watching it.  I also downloaded the screencast app. and I am going to try using that too.

Hope you don't mind, but your presentation brought up another question.

How did you do the section operation at the end.  I thought sectioning was only in drawing section.  In the texts I have I can't even find the section tool being available in design section.   I did notice in what I can 3D viewing you appear to move the aft clipping plane Hal-way across the solid and then rotate it to show it is solid.  If so, how do you control this viewing plane?

Is the dark area on the left edge of your window some sort of extension that keeps reporting commands?

I am in awe of how easily you accomplish things.

I hope my Screencast of the Sectional Analysis tool located under the Inspect menu drop-down is helpful.  As I mentioned in the video, you can create the cutting plane from any flat face, a workplane or an origin plane.  You can also adjust its position before accepting it.

The dark area on the left side of the Screencast video is just what you said, a reflection of the commands.  You can follow the commands a lot better by looking at the table below the video.  That dark area can be hidden by left clicking the nearly invisible "X" in the upper right hand corner of the dark area so you can better view the browser.

Thanks just what I needed

How did you make the line between the two surfaces?

Hi, Sorry but I did not ask this question or work on the original model

[jhackney1972]

This is an old thread and since the Screencast is gone, I really do not know what you are asking or what I did in the original post.  If you attach your model and define what you are looking for, I will be happy to take a look.  I would suggest that you create a new Forum thread and get off of this old one.  When you create it, if you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.
