All I am looking to do here is thicken this part to 3mm but it wont allow it and I cannot find any reason why. It will thicken without the filled surface in the middle.
Thanks in advance for help.
Your last 3 knit features are wild. Delete them and use only one knit between surface bodies, not faces.
This is a common mistake, when users pre-select faces and use them in knit, instead of using surface bodies.
The surface can be thickened outward 3 mm. See attached.
Are you looking to thicken outwards or inwards. The above solution will solve your problem for thickening outwards.
Cheers. was just looking to thicken outward.
