This is indicative of the problem.
I need to measure the projection of the pin from the support block. I need equal projections at each end, just for the sake of neatness, and I then need to cut grooves in the pin for retaining clips.
I have a workplane set on the face of the support and both the support and pin layers are unlocked.
Orthogonal & Quadrant points give me the clearance, as does vertex.
Intersection will not snap. I am assuming because of the clearance.
Grid is clearly not appropriate, and I am not sure about nearest on graphic or facet will give a correct measurement but whilst they show a dimension it disappears?
Parallel likewise returns an odd dimension, looks like clearance but too big.
Likewise if I move the workplane to the axis of the pin I cant find anything that will snap to both the end of the pin and the face of the support.
This is the problem I am having all the time, effectively the same as before when trying to snap a tangent to the clearance ring.
So where am I going wrong?
There is of course a way round this one; by dimensioning the gap between the supports & the thickness of the supports, adding then, and then transposing?? that dimension to the pin, cutting the groves, and adding the extra land equally at each end. Does seem a roundabout way of doing it though.
