Projected Sketch Question

[Anonymous]

Hi guys.  In Fusion, when I project model edges onto my sketch, it seems that they can not be altered in any way.  In SW, after I extract and edge (or offset an entity), I can trim it or extend it as necessary to make a closed sketch.  What is the best practice for fusion?  Do I draw a line over top of the projected line, or add a short line segment to the end of the  projected line in order to close the sketch?

Maybe its better to draw a line and constrain it as collinear to the other body's edge?  This seems very clunky to me.

Thanks,

Walt

Yes, your understanding is correct.  Projected sketch entities in Fusion are not editable.  

The recommendation kind of depends on your usage.  You should rarely need to trim geometry in Fusion.  You can just connect lines to the projected geometry, and you can recognize sub-regions of the sketch.  If you really do want to "trim", then, my recommendation would be to convert the projected geometry to construction, and sketch a shorter version over top of it.  

For "extend", yes, just tack on another line that is colinear (for lines), or a concentric arc (for arcs).  Splines are admittedly tougher.

Hi Jeff,

I'm curious why such a useful and seemingly obvious capability (i.e. being able to trim the sketch entities of projected geometry) is not part of Fusion.  After my recent experience (below) I question if "You should rarely need to trim geometry in Fusion." is the reality.

By way of example, I just got through editing sketches created with projected geometry off of a complex STEP assembly import that came in as multiple open and closed bodies that I was unable to do much with (i.e. couldn't convert to DM, stitching efforts failed, etc).  It would have been a godsend to have the above mentioned feature, instead I spent hours manually editing and replacing sketch entities until I could get the geometry into closed profiles.  I too came from SW and really would have like to have its sketch capabilities for this task.

Thanks,

Art

I found this thread when coming up against the same problem. The workaround is to use the Offset tool instead of Project, and set the offset to zero.

Sometimes Project will pick up geo Offest won't. in that case, Project a construction line then zero-Offset that construction line.

Why *wouldn't* you want to edit projected geo? Otherwise what's the point of the tool?!

I believe you are looking to edit a sketch after projection, If you right click your mouse and choose the "break Link" command the line or lines highlighted will be free to edit.  Hope this helps....

Your Offset suggestion worked very well for me @Anonymous 

It generated a Sketch that I could export as a DXF, and then open in Adobe Illustrator; normally DXF files I export from F360 will not open in Illustrator.

I love your "Break Link" suggestion to make Projection Sketches editable, @Anonymous but it did not work for me.

When I right click on a line created by Sketch-Project, Break Link does not appear in the context menu. Does anyone have advice for getting this to work?

Things have changed, there is a toggle for Keep the link in the Dialogue Box.

Editing the correct sketch?

Selecting a purple article should have Break Link in that menu, 

Might help....

This "Break Link" method works perfectly @davebYYPCU 

It lets me create a DXF file that opens in Illustrator and is editable like a file created in Illustrator.

And thanks for the Break Link idea @Anonymous
