Hi there! I am having an issue with the offset to not working when my sketch includes the spline tool. I’m pretty sure the design is closed Because I can use other tools such as extrude and shell. Is anyone else having this problem or am I not doing something right? Thanks in advance!

Hi @4monkeys Welcome to the Forum 🕶  
Thanks for explaining what you have tried, it would seem that **Sketch \> Offset** should be working on your **Closed Sketch**.

This shows **Sketch \> Offset \> Loop** has worked with a Spline as part of a **Closed Sketch** :

1. Can it be assumed that your **Closed Sketch** is filled with Light Blue as in the above ScreenShot?
2. What Offset Type(s) have you tried [Loop or Single or Both]?
3. Create a New Design and replicate your **Closed Sketch** then try Offset again.
4. If Offset is still not working for you use one choice from Sketch \> Circle/Rectangle/Polygon/Ellipse to create a **Closed Sketch** and try Offset with that.

Shout if you still need help.
