I have a side view of aircraft, many rivets to be drawn on the side view plan, which in effect is drawing on the CPlane as the Cplane sits down centre of aircraft, like a piece of paper sandwiched between two plastic kit halves !
then I need to project these onto the actual surface skin port and stbd.
I need to keep memory down, so remember the advice to use block command.
I create a circle, then type Block and choose the circle and the centre.
I then create another layer and make active, select the circle and run copy command, choosing centre for point to copy from, place a few copies on my ‘centre plan’
Then decide the circle and its block instances need to be bigger so I go to the circle I made a block command of, alter its diameter, nothing happens to the instances, should the copies not also take on the size of the new diameter ?
I cant see how to make the instances (children) update to whatever I do to the ‘Mother’.
That aside, if I project these onto the skin, will I lose the advantage of block ?
How can I get their projected images to also keep memory minimal ?
In other words, how can I create loads of circles on my surfaces and stop rhino from slowing to a halt ?
