Understanding Furniture Location fields
being able to upload a screen shot would be a huge help for speed and understanding.
trying to explain in text takes ages and is apt to confuse. =====
we have the Location fields and the Size fields.
ok. the Size (Dimension) fields are straight forward, and Elevation field in Location is also simple and works fine, so what is left is what i do not understand where the figures come from.
eg i have a Furniture object on the wall LHS=100mm (Wall): but X does NOT display X=100mm, nor does it display x=803mm (width+100 ie the front of object)
instead it displays 458mm - which is the problem. what IS this figure???
ditto the Y figure displayed - 3.952m - which again does not seem to relate to anything.
the issue would be obvious on the screen shot which displays both the Location values and the actual object and X/Y axes values.
and despite looking at 20 pages of hits (out of over 1,000, 10 at a time!), i see nothing. and there is exactly zip in the Manual under Furniture about the Location fields.
so what is the answer? where and what are these obscure Location values coming from? because, one thing for sure, they are not any of the obvious Location values.

Re: Understanding Furniture Location fields
The furniture location is displayed as the center of the furniture object. So if you set the X and Y of an object to 0,0 it displays with the center at the 0.0 position. In other words: an object with width 100 and depth 100 with location X,Y as 0,0 will have it's top left corner at -50,-50 and it's bottom right corner at 50,50.
The object location is not related to it's position on a wall, it's independently related to the plan/grid.
Wall dimensions are measured using the center line of the wall and start-end points of the wall as is explained in this forum dozens of times before. It's a design choice to allow other calculations and placements and works fine if you know it does use that center line.
My advise is to start with a wall with round numbers (W10, L1000, H500) and an object with round numbers (100x100x100) and learn what the coordinates are when you place the object against the wall. Exact placement can be done by setting the X.Y, not moving by cursor or mouse. So place the wall at startpoint 0,0 and endpoint 500,0. Then see what the object coordinates are when you place it against the wall. Observing will teach you how cordinates relate to the object position. The round numbers derived from 100 will be easy to recognize.

Re: Understanding Furniture Location fields
The help page about furniture modification states "In the furniture pane, you may change its name, the abscissa (X) and the ordinate (Y) of its center". Center is used because it won't change according to the rotation angle.

...excpet this appears NOT to be correct. in my example (that i cannot upload! how much time and effort would it save?),
the Furniture item LHS is at 0 on X axis, and its Depth is 703mm. the "centre" would therefore be 351.5mm; but the Location field actually says "458mm"

Re: Understanding Furniture Location fields
I don’t know what you mean by "LHS", and unless you rotated the piece, comparing X and depth isn’t correct. With a rotation of 0°, the width of a piece is measured along X axis, and its depth along Y axis.
