Unable to Create Fillet, Too Complicated

[alexap9982]

So I'm trying to create this fillet that I managed to do just fine on the other engine, but no matter what I do, I am CONSTANTLY getting this "Fillet too complicated". It's extremely annoying and I can't get past it. It's at the point now where it is delaying my work. I need the radius to be 8 by the way. Is there something I'm doing wrong?

Still having issues

Hi! Please take a look at Work Plane28 and enable Half Section View. Zoom in to the area you are trying to fillet. You will see the undesirable WTH geometry.

Are you a student? I took a look at the design. Though it is very impressive and very nice-looking, the modeling technique is not robust. How did you learn to use Inventor? A 3D feature-based parametric solid modeling tool like Inventor creates body geometry precise up to 0.00001mm (sketch geometry up to 0.000000001mm). The geometry cannot just look nice but it has to be precise and measurable. You leverage an image and use spline curves extensively. I guess you are trying create a printable model. Please make sure the sketches are dimensioned appropriately and the geometry is as simple as possilbe. Loft should not be the first command to use.

Many thanks!

Thanks for the reply. This is my first plane modelling I have done, and yes, I am a student and I am using the educational version of Inventor. The model is indeed being made to 3D print on my home 3D printer. I know it isn't the best, but at some point, detail will hurt the print. I did find a simple error to the extrusion, but now I am having this problem (at least it shows this time). Why is the right side doing this and the left side not?

Outstanding job, Alex. You're an artist.

Only a slight change in Sketch45 was needed.

Thank you so much dude. 😀

If you could please tell me what you did, so I can hold that knowledge for future reference, it would be extremely helpful.

See circle in screenshot. All curves must meet in a common point.
