i have imported a step file from another programme and need to do a 2D plan of it with all the measurements. in some parts of the body, straight lines are combined with curves and i would need to split them into separate straight lines and separate curves in order to put measurements on them? is there a way that shapr could do this for me? just adding reference points where the straight lines start curving would also do the job?

Hi,  
I don’t know if I understood correctly, but if not I will use the Tool \> Project.
