Strange 2D artifacts on drawing

k.hendrickx — Mon, 10 Mar 2025 11:21:38 GMT

Hi all,

Sometimes, when creating 2D drawings based on 3D assemblies, we end up with these weird artifacts spread around the sheet.

Now we narrowed it down to parts that basically get exploded in the view, but we can't find any way to rectify this.

Starting a new drawing just results in the same weird lines that don't match with the 3D model, of course.

Same view, but in the 3D environment:

We know it can't be because of the 3D model, since these get used in hunderds of projects without any problem. And even in the same view, some of them do get it drawn correctly.

So anyone who has a clue what's going on?

With kind regards,

Ciao, io ho notato che utilizzando il comando "ricrea tutto" nel modello 3D il problema (a volte) scompare.

Ma non so se è la soluzione corretta!

Hi! The part body may have bad geometry. Open the part or assembly of interest. Press Ctrl+F7 (make sure you have C:\Temp). Is there bad body reported? If yes, please open the part and select the base features -> right-click -> Repair Environment -> Find Errors -> Heal Errors. After that, do they appear correctly now?

Please feel free to send the files directly to me (johnson.shiue@autodesk.com). I would like to understand the behavior better.

Many thanks!
