Did you attach the same part as that shown in your image?
In the part attached the Sketch1 (8) is not fully defined.
It is not at the origin - which would make logical sense.
I recommend starting over from scratch and post file here after first sketch completed.
I doubt I would be creating more than 2 or 3 workplanes for this design.
I doubt that I would have ANY unconstrained sketches - so as soon as you have one - STOP and attach your file here.
different photo but exactly the same problem on the same bit of the part.
I understand the sketch in undefined but as a concept it is working so far for me, a few people were able to fix the problem last time which is what i am trying to achieve.
as for the workplanes I would love to be good enough to make this only using two or three workplanes but I am trying to teach myself how to use the program as I go,
Thanks for the help
Instead projection curve make a split line on this same face. This is for the Loft9 feature.
Then you can use a face, sketch 52 and sketch 39 as profiles for your loft feature
Check Merge result in loft options as this shoul give you a single body.
Thank you I've looked up and used the split line feature and it worked!
