Hello thank you for reading this... I'm new in Solidworks and I have problem when do sketching which is I cant make a circle with dimension is 1000m diameter as shown in picture..Please somebody help me and sorry im not good in English

SolidWorks will automatically add relationships (to "help" you) and I think there is a horizontal relationship between your big circle and the small circle to the left of it.

First, delete that big circle and save the sketch. (This will make sure there are no other errors.)

Next, edit the sketch and draw a new circle. But this time draw it lower down (away form the other circles).

NOW you can dimension the circle and add dimensions to locate it relative to the origin.

You goal is the end up with a fully defined sketch (all lines should be black. No blue lines!)

Well spotted Kelvin Lamport. This part is indeed in meters.

However you are a little off regarding size limits. I believe that all elements must be within a bounding box with a side length of 1000 meters and center at origin. This means that a circle of 999.9999m can only exist if it has its center at origin.

Assemblies has a greater limit - if any.

I once modelled a railroad track for a large factory plant, and had to make it up from small squares. Not as easy as it sounds.

SW has a sketch element limit of 1000m.

Workaround is to make the circle 999.999999m
