Hello I'm relatively new to solidworks and I am trying to make a basic BMX helmet for a project. However when I try and thicken the model it comes up with the error unable to thicken the surface. Ive attached the file and any help would be greatly appreciated.
Thanks in advance
There are few discussions about this - Please search to find the solution
If you look at the top of the helmet, you have a "pinch point". I don't know what else to call it. Get rid of that, and I think it would work.
Agreed with Ken
You need to fix your first boundary feature for all constrains and guide curves - see the bottom image
Hello Toby,.. although not ideal, make sure your 4 sketches which meet at the apex all have Horizontal end constraints so they align with eachother..
I think problem is in strange navel at top
