Trouble with constraints

steven_wild286

Hi, I'm new to Onshape, creating my first design. I'm having trouble trying to get all the lines constrained, and hope someone can help.

Here is a link to my file. I clicked on the "Copy document URL" button, so I hope this works. (I'm also new to using forums...)

Here is an image of what I've drawn. I offset the inner lines and connected them, with a view to extruding the shape once I've fixed the constraint problem.

Thanks for any advice.

Welcome to Onshape! This is a great start for your first design. Sketch constraints can be tricky to see if you aren't use to them. Here is a quick Gif showing how to finish constraining your sketch.

• A few points were missing the Coincident constraint. 
• The bottom left corner was over constrained somehow and needed to be re-made. I used the extend tool to remove its constraint to the construction line then re-apply it.
• The bottom right was only missing some coincident constraints. Alternatively, some vertical constraints could have been used instead, however if this part is rotated in the future, this way ensures that the lines always stay coincident with the construction lines no matter their orientation.

Thanks very much for the reply. I'll spend some time studying your solution to make sure I've got it.
