![]() Then delete the 500mm constraint and join the vertices together. What I suggest you do is change one of those 400mm constraints to 500mm and see where the box separates. Most likely some of the vertexes are close together but not actually coincident. Since it is letting you do that, the box is not actually a box. Sketcher won't let you create a box (with horizontal and vertical line contraints) that has two parallel sides, both having a length constraint. ![]() ![]() If all the vertices were coincident, the Sketcher workbench would throw an error that your sketch has redundant contraints. It looks like you have two vertices that are not coincident. If you look at the circled bit here, you can see two parallel line sections that both have a 400mm vertical constraint. ![]() You have at least one problem I can see with your sketch that's preventing it from Padding correctly.

I copied your "Clamp handle" sketch to a new file and edited it to show what I mean. You should have a tangent constraint wherever an arc meets a line or another arc. One problem is that your sketch contains only a single tangent constraint between a line segment and an arc. You should always prioritize use of geometric constraints where you can instead of dimensional constraints. I would also like to provide more pointers: your clamp handle sketch contains way, way too many dimensional constraints - this is bad practice. You must trim the circle using the Sketcher trim tool. Your sketch does not meet this condition: the handle is attached to a full circle. It can contain "islands", or smaller closed profiles, but they must not cross or be tangent to the outer profile. To produce a valid face, a sketch must contain a single outer closed profile, which must not be crossed by other geometry. Internally, when creating a Pad or Extrude, the software must first create a face out of the provided sketch, then extrude it in the 3rd dimension. I'm guessing you are talking about the sketch labeled "Clamp handle"? It is to be expected that padding it would produce such an error. It is not often that newcomers make such detailed posts and supply their FreeCAD info as well as a FreeCAD file.
