need help creating object with differnt width/depth on all 4 corners

Hi All,

just started with onshape/cad drawing and need some help.

I needed to make a spacer for for a turbo airintake , and managed to make the right shape, but I just can´t get the depht/width right.

The object should have a different depht on all 4 corners, can anybody help?

You could put mate connectors at the correct depth at 3 of the corners. Then make a plane and split the part.

Hey Jack. The top surface is curved? The bottom surface is flat? - Scotty

@Matt_Shields ,

thanks for the help Mat, but I just started with whole 3d/onshape and learning curve is quit steep.

could you elaberate a bit more, I managed to make a new object whitout the imported image file in the back.

where should I start with setting the mate connecters? edit sketch1 or the extrude?

@robert_scott_jr_

both top and bottom surface have a curve in one corner, are the same.

@Matt_Shields ,

Thanks for the help, this is what I meant.

but I have to learn more about using the mate connectors.

the base depth at the curved corner should be 20.5 mm , then mate connector 1 should have 8mm depht,

mate connector 2 should have 2,5mm depht, and

mate connector 3 should have 15mm depht.

But when I set base depth with extrude, it doesn´t correspond with actual depht when I use dimension tool to check measures.

Have to read more manuals I quess.

I'm lost what you are trying to do. Are you trying to make an angled spacer to go between the plastic commercial part you shared in post 1 (as a picture), and a piece on your car?

Off topic, why did you use a transform to scale your part? Why didn't you draw it initially to the size needed?

Yes I´m trying to make an angled spacer .

I scaled my part cause I initialy started with an image/scan of the outside lines of the part , and then draw over the lines to get the exact angles of the part.
