Caddie 10 and later

Question:

I select some objects and I want to place them at a specific distance and direction relevant to where I pick the object from. I specify it using a X ,Y  & Z co-ordinate but the object ends up in a completely different position. Why is this and how can I stop it happening?

Answer:

There are two ways in Caddie that the measurements are done.

ABSOLUTE (ABS) - the default in Caddie

flag absolute

Absolute will always make measurements from the UCS origin by default

So 0,0,0 will be the Zero Origin of the User Co-ordinate System (UCS). The UCS is on the World Co-Ordinate System (WCS) by default.

The UCS can be moved, so therefore the absolute position is also moved.

If when typing in the x,y,z co-ordinate value, it is preceded by a hash (#) - #0,0,0, the absolute measurement is made from the absolute position of the WCS.

RELATIVE (REL)

flag- rel

Relative measurements are always taken from the current origin in the drawing, which is indicated by a small white rectangle.

Conclusion:

The reason your selected objects where moved to a position which you were not expecting was probably due to the fact the ABS flag was set and not the REL flag.
