Solidworks Revolve Error - 'The Sketch is open, self-intersecting or intersects the centreline'

A common problem when trying to make Revolved Boss/Base or Revolved Cut Features is the Sketch Error, "The Sketch is open, self-intersecting or intersects the centreline".

To fix this try:

1. Check that your Sketch isn't open. This means that you need one single, closed profile with no gaps or breaks. Try using an Extruded Boss/Base to check whether your profile is closed. If you can't Extrude the profile then it probably isn't fully closed. You can also use the Select Chain (right click on any line in the Sketch) option to help find gaps.

Note: the lines of the profile must be solid lines. Construction/Centrelines count as gaps in the profile. Make them solid by selecting them, then unchecking the 'For construction' box on the left.

2. Check that the Sketch doesn't self-intersect. This may be lines crossing over themselves/overlapping, or it may be single lines that are only connected at one end. This may also mean there are two lines drawn in the same place, one on top of another. To help find these use the Select Chain option again.

3. Check that the Sketch doesn't intersect (cross over) the centreline. You can have profiles on both sides of the centreline, as long as you don't actually cross over it.

By checking these three areas you should be able to find and fix your problem. If you're still stuck then drop me a comment below and I'll try to help.

Thanks for watching, and happy modelling!

Fantastic! Thank you. You're an excellent teacher. I spent countless minutes trying to figure out why my complex sketch was not revolving. After watching your video, I finally figured it out. Gratitude!

9:57 Don't know how a dynamic mirror can double a line but you solved my problem. Thanks Johno

[albertzadourian]

Thank you. The issues I had never heard even from my instructor is explained and I found my problem.

[Ryanjedi]

Thank you so much. I had a really narly sketch that I couldn’t find the problem in. Thank u!

[gmerelygme]

Thank you for this video, I have been struggling and I didn't know why until I saw your video. Thanks you

[hayzeqeiqbal]

finally, this stuff is never found in my lecture or perhaps I missed it. Thank you, sir.

[blazingamr]

Thank you very much. One minute into the video and I found out a solution 👍💖

min 5:27 was golden. I had to delete and then select chain again.

Thanks brother,
Concise, exhaustive, easy to understand & with live demonstration explanation. Starting from the problem statements kept me concentrated on video up till last. How many hours you devoted for making this nearly perfect video?

[airsubzero]

this should go under Life-saving Category

[ignatiusebo-quansah]

Thank you, this was all that i needed 🤩

[kwalsk]

How to find self intersecting lines efficiently? Thank you!

[rodvinskyd]

Ok now how do you make the program automatically detect and delete overlapping edges and merge endpoints so we don't have to spend hours going through hundreds of lines?

[ionapostol]

You don t explain at all about overlapping lines and how to remove it
