Drawing section view error

[102169026]

hello,

first time attempting to create detailed drawings using inventor. I'm trying to create a section view (F-F C3), which is a section at an angle, however some details are or appear to be missing. is this because there's an error in the original part? drawings attached.

any help appreciate thanks

I can't look at your .idw as it is in Inv2026, I'm still using '24. Can you upload a PDf of the drawing.

here you go.

Attached is what I get from your model. Views are arranged differently as I think you are working with 1st angle projection, I use 3rd angle.

I tried a Rebuild All on the .ipt file and got two errors-- a sketch coordinate system error on Sketch22 and a "doesn't do anything" error on Hole2.  Perhaps if you fix those the drawing will be happier?  But I don't know what would cause the multiple missing edges in the drawing view.

I can remember a couple of parts that did this years ago but I don't work there anymore. I think one was a pipe elbow that was ever so slightly not square with the view and the other was on a cast housing, some sweeps I think.

I think the problem is there are some places where a line overlaps those edges and Inventor still can't, after ever so many years, figure out what part of that edge to not show. It's made with a coil or a sweep or maybe a loft, right?

I can't quite get the right search terms to find the discussions, and it doesn't help that they won't let us go all the way back anymore.

Hi! This is usually model geometry related. Revolution3 seems to create problematic geometry and the drawing section view cannot properly shows the section edges. The quickest workaround is to create a zero-distance offset surface in the part (Thicken -> Surface -> window-select all faces -> set distance to 0). Hide the surface. Then go to the drawing and edit the view -> Recovery -> check "Include surface bodies."

After that, the section views will be displayed correctly.

Many thanks!
