Depicting a burned out profile before and after maching

[DMiller01]

I have seen refereneces to this type of problem before but I am currently unable to find it so I apologize in advance for posing what is probably a familiar question.

I have a steel plate whose profile is burned out to the approximate part shape. Material will be removed from the perimeter to create the finished part. I need to provide a drawing view of the burned out profile to provide the vendor. I also need to provide a finished view showing the part after it has been machined for our machinist.

The situation is analagous to showing a cast part before and after machining. I modeled the part to the size of the burnout. I added machined features like mounting holes. The last feature I modeled was a extruded cut along the edges representing the material that would be removed to create the finished profile of the part.

I would like to show the parts without any machined features in a view on sheet 2. On sheet 3 I would like to show the finished part with all machined features including the edges that where milled back.

I have tried to use layers to move the last feature to an other layer where I can make it invisible but it appears that features such as extruded cuts can not be placed on individual layers. I could suppress the feature when I print out sheet 3 and unsuppress it when I print out sheet 2 but there has got to be a better way of handling this.


By the way, in case this has any bearing on the situation, we do not use "master model" for our drawings. The drawings reside in the part file.

Your best approach would be after you have created the first representation of your part model, be it the as burned or the as machined model (whichever is your design workflow), make an associative copy of the model using...

Insert -> Associative Copy -> Extract Body...

...and then make the changed needed ON THE COPY to get the second representation, burned or machined. Now you can place each of these bodies on their own layer and you should be able to get the drawing results that you're looking for.

John,
I did as you suggested and it works great. There's another tool for my tool box.

When we do this with profiles that have post cutting machine ops, such as weld preps, we create WAVE link of the body (in the modelling side of drafting) and ensure that the WAVE link is created at a time stamp, we can then extract the flat pattern which will be used to create the DXF file for the laser cutter and the we then add a suppress by expression to hide the WAVE linked body. This means that where the component is used in a WA, it is the finshed article and it also doesn't mess up our weight calculation that is added to the drawing border as an attribute that us calcualted from the final solid of the master model.

Not sure if this is method is any use to you, but it works very well for us.

Life shouldn't be measured by the number of breaths you take, but by the number of times when it's taken away...

By the way, why these links called "WAVE"? any connections with the waves in the ocean?

I belive it stands for something along the lines of ?Advanced Vehicle Engineering although John will know better than I do. (-:

Officially WAVE was an acronym for What-if Aternative for Value Engineering, but now we generally consider 'WAVE' to simply be a NAME for the collection of functions which allow items, usually geometric objects, to be associatively shared between different Part files, and therefore is no longer used as an acronym.
