Sketch in a drawing

[Anonymous]

ok, I am wanting to go into a sheet metal flat pattern drawing, I want to add a point or cross hair on the drawing and then dimension from edge of part to the point or cross hair. how can I do something like this inside the drawing only but also use the geometry in the drawing to dimension it to?

Click inside the view boundary.

Hit S on the keyboard.

Project Geometry if needed.

Thank you, that worked but when I close he sketch I can no longer see the sketch and dimension I put in???

Instead of using a sketch point do a couple of lines and trim with a circle (you can set the circle to Sketch Only).

or

add the sketch at the part level and then Retrieve in the drawing.

You will have to sketch a cross (to represent the point) using lines. Then, dimension from the edge of your part to the sketch lines. If you placed a point in your sketch, it will disappear when you exit the sketch.

When you exit the sketch, the dimensions will be hidden, but you should be able to still see the sketch lines.  Now use the dimension tool to place your dimensions to the sketch lines. You are sort-of doing it twice.

You could use "Retrieve Dimensions" in the context menu and bring the sketch dims forward if you wanted to do that.

I normally do any special flat pattern edits in the model. This way it's easy to export for CNC programming (which is normally why I need it there). It can then be retrieved into the drawing if I need to show it.

OR
Create sketch as JD describes, close sketch and use retrieve dimension to show the sketch dim
