In a standard IAM you can create a Sketch,
but in a Weldment, you can't in the main IAM enviroment. Did something change,
or was this functionality never there.

Sketches are enabled when Preparations or
Machining is active.

Loren,
I appriciate this is an old post, but I got a good reason to have a sketch in a weldment.
To help place a work feature
Take a hollow hemisphere
Make a hole through the shell that is off-centre from the middle, but parallel to the centre line
You have curves in all three dimensions, so placing work planes accurately become difficult
I now need a work point that is in the centre of the hole and aligned with the outside of this hemispherical shell
I also want to put it in with the least number of work features to keep the file size to a minimum.
I would put a work axis down the hole and a work plane between the centre work plane and the one down the hole.
Next I would put a sketch on the work plane a project the geometry
Where the sketch geometry crosed the user work axis I would put a work point.
I'm open to any better suggestions as well
TIA
Sounds like the same thing I'm trying to do.
Workflow is:
Open weldment
Create specific planes for nozzles on tank head ( for repositing on head later)
Place tank head from standards library
Start machining
Create first cut for vessel inlet flange
Create sketch on vent nozzle plane at desired angle
This is to produce a hole cut thru the tank head (for locating the pipe/flange later)
When trying to create an axis and point the workflow comes to a screeching halt
Inventor 2013 will not allow me to perform those tasks
This workflow is more desirous than copying/renaming the standard tank head just to make cutouts.
Then placing that .ipt into a weldment.iam. What would be the point of having a standard tank head if you can't perform these basic tasks.
