Can anyone tell me what I'm doing wrong here?

[Anonymous]

Hi all,

I'm pretty new to this software, so I apologize in advance if I'm overlooking something really rudimentary. I'm using Fusion 360 to design a project for 3D printing. The whole project will have some... unique geometry, such as circles emanating unevenly from a central point and such. I made the prototype in TinkerCAD and am trying to "convert" it to 360.

I'm just trying to make a simple geometry for an extrusion, but 360 won't recognize it as a shape, so it can't be mirrored or moved. I have used the dimension tool to give it constraints, but it still won't complete the geometry. If I try to add any other constraints, I get a warning/error that the object is then over-constrained. Also, I can't extrude the object while editing.

I'm attaching a screenshot for reference. I have already spent over an hour looking online and watching YouTube videos, but I'm not really finding anything relative to my issue. Thanks again and I really appreciate the assistance.

Hi,

1. please share the design
2. explain from which sketch you want to create an extrusion
3. show a picture of a real existing object what is to be created in the end

1. Here is the link to the share - I'm using the personal version, so I can't allow downloading:

2. I'm trying to make the light blue shape in the screenshot into an object to use for mirroring and extrusion.

3. I can't share a picture of a real object as this object does not exist, I'm trying to create it for this project. It's only purpose is to extrude/cutout a window into the Pyramid sides and won't be actually printed on it's own.

Thanks a bunch for the response.

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

Attach your TinkerCAD file too.

Hi,

Although I could not view the file I will try this screencast.

Maybe this is what you are looking for.

Apologies, I'm still getting the hang of this. I have attached the file below. Thanks!

This is definitely the concept, only the cutout is not a straight forward polygon and that seems to be what is happening. I've been doing more reading/searching and it appears that I may have to use sculpting to get shape. I have attached the project file to the thread. Thanks again!

Is something like the Attached what  you are after?

That's it! Without pushing my luck, is there anyway to show me how you did that?
