Mouse coordinates and point list coordinates issue?

[nivagc]

Hi All,

I have a problem!!
Attached is a digitized engine sump I’m sand casting of which I need exact coordinates.
Question?

Are the mouse coordinates (bottom right) an exact position?

Zoom in on point list (11576) and according to the Mouse position it’s X 0, Y –198.0470
However in the Points list (collection) on the right preview plane it states X –3.42494000630737E-05 Y –198.047061966102

As you can see the Y is not far off however the X is.

What is the problem, how can I get the complete drawing to move to Point list (11572 and 11576) to X position 0?

I hope this makes sense

Many thanks for any ideas

Gavin

I think it's because Z has a negative value at that point and it is giving the mouse a wrong value for x. If you set 'snap to grid' to False, the reading becomes more accurate because it is not snapping to the nearest point.
To move the whole drawing so that a pont is on X0, Y0, make sure 'snap to grid' is set to TRUE, select everything by dragging a mouse box over them, select Edit --> Transform --> Move , click on the point you want to centre then move the mouse until it snaps to X0, Y0
Hope I've got your requirement right.

Nah... just read what it wrote:

X –3.42494000630737E-05 Y –198.047061966102

which is scientific notation for

X –0.0000342494000630737 Y –198.047061966102

If you ask me that is damn close to X 0, Y-198.0470, just round to 4 places.

After the "E" it tells you how many places to move the decimal point, negative moves to the left, positive to the right.

Best,
Don

Ha ha I failed to see the scientific notation, that explains it.
