How to? Linear Dimension alignment

[tkell...@my-dejanews.com]

I am trying to modify the Autocad dimension comand, in order to allow me to
align a series of continuation dimensions in a horizontal or vetical line, by
using the point filters .X and .Y

I dont want the dimension lines crossing the drawing to reach points inside to
outer profile of a building. I want all the dimensions in one-line, for all
wall positions. I can manually achieve this by using the following series of
commands, but I would like to automate the .X & .Y part of the command.

Command: Dimlinear (select first point)
Command: .X (Pick intersection within the building structure)
Asks for (YZ) (pick first point again, to give the Y co-ordinate of outside of
building)

(This placed the first dim line outside the building)

Command:dimcontinue Command: .X (pick the intersection of next internal
building element) Asks for (YZ) (pick first point again, to give the Y
co-ordinate of the outside again).

The above example is for a horizontal dim line, the only change for vertical
is to switch the .X for .Y.

Ideally I would like to be able to switch on/off a kind of Osnap function for
the point filters.

Thanks for any assistance in advance.

Tom
