The offset tool has all of a sudden started putting the offset edge on another plane and this is not what I want. I want it to be part of the existing sketch so I can extrude only a small portion of the sketches. How do I get Shapr3D working so it puts the offset sketch on the same plane like it used to.
It is still working this way. Show us on a video what exactly you’re doing to force it creating new sketch.
Use the project tool ,
In the video the two sketch on same plane but diferent sketch plane.
Just selecting a sketch portion on the target plane is enough.
I’m new user I can’t upload video so I used another upload service. This has been an issue for a long time. It does not happen all the time but happens at least few times per project. Offset sometimes creates new sketch.
I see you have errors in your previous actions, perhaps that’s why you get such result.
Here I’m doing the same actions and as you can see don’t get new sketch.
Ok. I understand why you get this behavior. You have another created sketch (sketch 2) and working from 3d modeling mode. You have to enter in sketch mode before offsetting or put a breakpoint before you’ve created sketch2.

Thank you I believe you are correct. I still need to grasp the offset concept you have described. But I now know what to look out for after the experiment you showed. I cleaned the history unhide the sketch, I believe the sketch that had the problem was a duplicate of the hidden sketch. I tried different method, one version created a new sketch and another that didn’t.
That’s not the offset problem. You have to understand how history is working. Then you make changes in last action they will be merged. But if you already did something else (create new different action in history) then new action will be created.
In simple words if you did something after creating a sketch you have to edit the sketch to avoid creating new sketch 
Or use a breakpoint in history.
I didn’t say it’s a problem, I just needed to grasp the concept of the offset behavior within Shapr3d and with your help I think I understand, but I still see inconsistency with it’s logic. My last 2 example at the end I selected the face of the sketch and it created a new sketch. The very last example I selected the sketch outline but the offset was now merged so I now know what not to do. So that behavior is not history based, it was just 2 different ways to create the offset face versus outline.
Off topic but other Shapr3d like software have offset constraints so this behavior in Shapr3d was bit perplexing, but now I know how it works here so I’m good.
It is. You just don’t notice that Shapr3d insert breakpoint automatically in some cases.
Then you select sketch outline you automatically enter in sketching mode. In this mode Shapr3D put breakpoint for you automatically.
You have to learn that there are to different mode of modeling one for working with solids and another one for working with sketches. In different modes you have different tools and different behavior.
I would recommend to read official manual from website.
I do not believe this offset behavior is in the manual.
My recommendation to read manual for you to understand how Shapr3D is working.
