Can you Attach your file here that exhibits this behavior?

Is this a new issue, it used to work but now it doesn't? Or did it never work correctly?

What are your system specs - especially graphics card?

What version of Inventor are you running?

How far is your geometry from the Origin?

Why are the same dimensions repeated multiple times?

Is your Display Quality set to  Smooth, Medium or Rough?

A *.png file is not a *.ipt file?

 

I added additional questions to my original reply.

The file you posted looks nothing like the images you posted:

One sketch containing four sketch blocks, all similar to what you see above.  Wrong file, perhaps?

This is most likely due to hardware/software performance. Your sketch is ~63 m; it's a lot. However, exact mathematical cylinders are created during the extrusion operation.

OK, I didn't zoom in far enough to see the circles!  And yes, it is very large for Inventor's math to work reliably, especially in graphics.

Hi

Your sketches are too far away from zero.

The sketch1 it's self looks okay at 31m, but the problem lies with the blocks.

The Blocks are over a kilometer from zero.

Edit each block and move them closer to zero, this will fix your problem.

Hi! The problem is indeed with the distance between the origin and the block definition geometry. Edit the sketch block "deel1." Move the cursor to the geometry. You will see the coordinate reading on the lower right is extremely large.

I suggest you delete the Fixed constraints and move the sketch geometry closer to the origin. Then the circles will be circles.

Many thanks!
