Machined casting drawings

Whenever we design cast parts we always leave about .125" machine stock. We
first create a cast part, insert the casting as the base feature in a new
part and "machine" off the stock. Is it possible to show the machined state
of the part in a drawing with the original machine stock from the casting
shown as hidden lines or something? I've seen lots of old hand drawings
done this way and it really helps the shop see what is going on. I've never
figured out how to do it in SW.

Thanks

 

We do have separate PNs and files (model and drawing) for the cast part and
for the machined part.
What I was wanting to do is have the original base part outline in phantom
so that one could look at the machine drawing and see quickly where the
stock is and isn't. The controlling document for the casting would still be
the casting drawing.

thanks.

 

I think you will need to make an assembly of the cast model positioned
coicident to a machined model. You would
then make your drawing of this assembly, rather than either of the
components. In each view, you can config the casting
component with a phantom or whatever line font. All the lines except the
machined areas will be covered up by the
visible lines of the machined component.
If the drawing is of a single component, you would not have any BOM
problems, since no BOM is needed.

One possible way to do this would be to put the machined part into an
assembly with a before and after machining configuration in the part
document. Then I think that you should be able to use the alternate
position functionality to show the as cast state as phantom lines.
Alternate position works off of configurations and you can pick which
configurations to show or let it auto create configs.

 

Insert a view of each part in the drawing. Change the line font of the
casting view to phantom. Right click the phantom view, select
'Alignment' and then use 'A;lign Horizontal By Origin'. Repeat with
'Align Vertical By Origin'.

I use this method alot when creating drawings of modified purchased
parts, such as a gear whose hub is cut off.
