Centering shapes in drawings, What tool should i use?

tom_scott

Hi, i'm fairly new to Onshape. Im after a simple way to center the middle rectangle - (width wise) within the larger rectangle. What tool should i use and how?

Thanks in advance.

I would use two "center rectangles" or I often connect a construction line from midpoint to midpoint, then use a vertical or horizontal constraint to lock the lines together.

hi all
(I know this thread is old but it very much describes the problem I am having right now)

back when using solidworks I used to be able to select the midpoint of a line in a sketch and then also select a midpoint of a previous sketch/feature then constrain them vertically or horizontal.

very powerful feature meaning they would stay in the middle no matter if I changed dimensions in the previous feature or the next sketch making revisions much neater and quicker


using a construction line or constraints with a  centre rectangle works but only for rectangles. I often do sketches where I want just one line constrained that way 


is there any way to do this in Onshape?

 If I understand your question correctly I would use a center point rectangle and constrain the center to the midpoint of a line in your other rectangle. Looked at your post again, you can put points(using the point tool) on center points of lines and contain only that point. I use that trick a fair bit.
