Sketch Plane causing offset bad geometry

Hello, I'm trying to create a second plate that needs to follow the exact curve on the side as the front plate, to do so I created a sketch plane on the back of the frontplate, projected the curve along the side and shaped the inside to my needed dimensions, but no matter what I do when zooming in the edge always seems to be out of line.

When zooming in the Sketch shows for whatever reason the sketch is offset from the original edge, I am choosing each edge to project one by one not selecting the entire body so I assume its not the front edge being projected


I dont this could be some sort of anti aliasing polygon loading thing becuase I took this model into Blender to render and found the weird uneven gap there so I want to make sure it isnt like that at all as this product will be made in real life

I was able to create a new front plate that is inline with everything but I have a new problem, The S edges down the sides of the front plate of the new model stick out and create an unwanted design, I attempted to fillet the edges but this resulted in deep unnatural cuts and I am unable to delete any face or combination of faces to remove the linesimage.pngimage.pngimage1.pngimage4.png

I need the flaceplate to be smooth is there any tips or tricks to remove this?

Hi all,

I’m running into a frustrating issue with a faceplate design in Fusion 360 and would really appreciate some advice.image.png

The problem: I’m getting visible surface artifacts (a seam or shading line) on the top face of a faceplate, where it should be completely smooth.

Here's the setup:

  • The faceplate is built as a solid component, created by extruding and combining the side and top plates.

  • To apply the front curve, I used a Loft Cut taken from the negative space of an imported OBJ reference mesh. The front curve is quite complex and couldn't be accurately recreated with sketches or dimensions.

  • As a result of this cut, unintended S-shaped curves formed along the sides — these weren’t intentional, just an artifact of how the loft followed the surface.

  • The unrendered view (third image) looks fine, but when lighting is applied (first and second image), a visible edge or seam shows up on the top surface, disrupting the smooth appearance I need.

I’ve tried fillets and chamfers, but they only made the issue worse. I’m looking for a smooth, clean surface for both rendering and production use.

My main goal:

I’m trying to achieve one of the following:

  • Completely smooth out the face on this existing solid model and eliminate the unintended S-shaped curves that appeared as a result of the Loft Cut,
    or if needed as its late in development 

  • Find a smarter or cleaner way to apply, create, or cut the original front curve directly from the referenced OBJ file without introducing surface artifacts or transition seams.

Any guidance on surfacing techniques, workflow improvements, or model repair strategies would be hugely appreciated.

Thanks in advance for your help!

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

Hi! Without seeing the actual design, I can only speculate. I think there is probably a tiny gap between the projected edges and the actual edges. If you delete the projected edges, does the profile still remains closed? You may consider using Push & Pull or create a zero-distance offset surface and extend the surface, instead of extruding the profile.

Many thanks!
