Many parts derived from one sketch w/parametric relations

Many parts derived from one sketch w/parametric relations

Many parts derived from one sketch w/parametric relations

(OP)
I found this question and answer useful so I thought i would pass it along.

Question:
What is the easiest way to make many parts that are derived from one sketch, so that there is a parametric relation between the parts and the sketch so the parts will update when the sketch is updated?
 

Option 1:
One way to accomplish this is to use weldments.  Create the master sketch as a weldment profile and use that sketch to generate weldment structural members.  Unfortunately, weldments do not update automatically even when rebuilt to reflect the changes in the profile sketch.  In order to update the structural members it is necessary to edit the feature, change the profile and then change back to the desire profile to update the member.

Option 2:
Another method to accomplish the desired result is to create the master sketch and create an extrusion.  Save the extrusion as a part file.  Create a new part file, go to Insert > Part and select the extrusion.  Insert a sketch on a plane that sections the profile of the extrusion, select the face of the sectioned extrusion and convert entities.  Close the new sketch and delete the extrusion body from the newly created part file.  The result is a sketch that is parametrically linked to the base part, so when the base part or "master sketch" is updated the resulting part files will also update.

RE: Many parts derived from one sketch w/parametric relations

Nice Tips. ...i also find this method to be easier and very stable and it seems a bit faster:(assuming you are adept with using ext. reference data, I outlined the steps below with very little details. If you need more details buzz me)
1. Start creating the driving sketch.
A. during creation of the sketch, make a block.
B. Save the block (to a specified swdata folder)
2. Exit sketch without saving
3. create freatures of the part or parts using the saved
block as a sketch. (Rem. to check the link to file box
when inputting the block into the sketch. Build all
feature or atleast the base feature from this sketch.)
