Modeling a toilet bowl in the inventor

[이슬이]

Is this modeling possible in Inventor?

If modeling is possible, please let me know how.

I tried to use the loft feature, but it keeps failing.

Please check the CAD file and Inventor file.

@이슬이 Can you attach your attempt in Inventor where its failing?

Loft w/rails should work just fine.

Yes, it is possible to model this in Inventor.

I would model the inside cavity first as a solid body.

Then I would model the outside and Combine-Cut the cavity from the main bowl.

Finally I would add the Flanges and mounting details.

Thank you for answer. As you told me, the loft proceeded, but it is divided into multiple sides, not one side. Can't it go on in one aspect? If possible, I wish there was a video for reference. Thank you.

The top profile (Sketch3) is not a smooth circle or ellipse, but is made up of hundreds of small line segments (Inventor reports 2206 dimensions needed!!).  Therefore, the exterior of the lofted solid is made up of hundreds of facets.  Edit Sketch3 and create a smooth curve, elliptical or even spline if necessary, to match that segmented curve.  Then loft using that curve.

I see, also, that none of the sketches are tied to the origin.  This is basic to good modeling practice.  I recommend that you use the existing file for measurements, then start with a new file to create a proper model.

Here is the loft created from a new template.  Very simple, assuming that the top is an ellipse and the measurements in your file are reasonably accurate.

Hi! The tiny faces created by Loft is because of the profile at the top. It looks like projecting from a mesh or dxf. You need to create an ellipse to replace it. The tiny line segments don't make sense.

Many thanks!

Hello Thanks to your help, the process is getting easier. However, if I try to proceed with the loft by drawing a rail, it fails, and even if I try to proceed through the patch, it fails. How do I get the toilet seat shape? Any help would be appreciated.

There are too many lines in the sketches for the loft.

Delete them or set them to construction lines. See file (2021 IPT).
