Yes, this would be very helpful.
Unless the sketch being placed includes some construction lines along the axes ( which is in not necessarily the case ) you are pretty much flying blind and end up having to do the modelling mentally or on paper before attempting the placement.
Showing the axes is a good idea, however, I wonder if that is always enough. The user is attempting to align a sketch, most likely to another sketch or some feature on a model. The axes, while being actual thing which the attachment is keyed to may not be clearly related to the respective features the user needs to align.
I wondered whether making blue lines of a sketch visible during placement would be a useful addition. That would mean the user could add lines to either one or both sketches to assist with alignment if needed. That seems a more general solution.
For example, in the demo screenshot above, presumably the cube is a pad of a square sketch. If the second sketch needs to be aligned half way along one of the sides, the axes indicator will not enable precise placement. Whereas an additional line in the sketch could be added at the right distance to aid alignment.
Below is a case I got caught out with recently. Having only the circle visible, I forgot the small offset. It looked correct but was off because it aligned the axes not the edge of the rectangle. If the full construction of the sketch were visible it would have been explicit and the misalignment would have been apparent.
Probably a simple sketch for placing a hole on a face is a fairly common situation and the number of solid lines does not give much to go on. Showing just the axes as suggested may or may not be sufficient. Also having the full construction detail visible would cover all possible cases.
Does this issue need a feature request?
