[#1]

I have made a sketch associated with a view, and projected some geometry to my sketch. the sketch is grounded and constrained.Problem is, when I update my assembly file my view will be updated as well but the sketch does not update itself,and the reseon is the projected geomtry has not updated. I am fairly new with inventor but have read alot regaring my question but could not find any answer.Please help me

[#2]

to add to my previuos post, I am using inventor2013.

in attached files you can see my drawing befor and after updating the assembly file

[#3]

Can you post the actual .idw (or .dwg) file?  Or at least post a screen shot of the view in Sketch edit mode with constraints shown so we can see the projected geometry and constriants.

With the new show sketch in IDW's I would put that sketch in the model not the IDW. IDW has always had an issue with IDW sketch not updating. This started after the show sketch was put in.

I've never had this problem that I can recall.  I wonder what specific circumstances lead to this happening?

[#6]

Yeah does not happen all the time mostly on models with radius on the outside edges like his. Not sure why but started after IDW was made to show sketches.

Thank you for your reply. I have attached some screen shots from my work.

I need to dimension different arc length on my rafter and also the cut bit at the tip of the rafter. As they are not actual edges, I have to project the geometry of the rafter and redraw some sketches on that and constraint it the projected geometry to be able to get my desired dimensions.

But as you see in the screen shot after I update my DIM ‘A’ in the assembly file, the view updates  perfectly but not the projected geometry. In the screen shot of the sketch after updating model  you see that the yellow lines of projected geometry which are not associate with the parent geometry.

If I am not clear again please let me know.

Many thanks,

please also see in attched file the sketch after updating the model.

Thank you James, I got it work with the sketch in the model. but as you said it happens with the projected geometry of on arc edges in IDW files.
