https://forums.autodesk.com/t5/inventor-forum/holes-in-beams/m-p/5587356#M380152 <P>...to elaborate on Blair's comments</P> <P>there are actually several environments in within the Welding environment including Preparations for "prep-machining" done before welding, Welds, and then post-weld finish Machining.</P> <P>&nbsp;</P> <P>Sheet metal must be done at the part file level (which can be done within the weldment assembly).&nbsp; When r2016 becomes available to students be sure to check it out as there are significant sheet metal additional functionality in the latest release.</P> <P>&nbsp;</P> <P>For future questions - you should take care to fully define the problem statement and design intent.&nbsp; It certainly would have been helpful to know that you were in the Weldment environment.&nbsp; SolidWorks does weldments as multi-body single parts that are then pushed out to assembly and individual parts.&nbsp; As a Weldment is in fact an assembly of components - Inventor does it as an assembly from the start.&nbsp; Because of this - there are slight differences in logic.</P> Sun, 12 Apr 2015 10:38:54 GMT JDMather 2015-04-12T10:38:54Z
