I offer the following tip for you and your
Upon my return to AutoCAD, after using AES (Architectural & Engineering
Series CAD program), I found AutoCAD was missing one very handy feature that AES
In AES it was possible to draw a line from any point to the X or Y component of
any other point.
I was aware that AutoCAD point filters could be used but found them to be very
After a bit of poking around, I found I was able to automate the point filters
and created the 'X of...' and 'Y of...' object snaps in the POP0 menu as shown
The POP0 menu is found near the top of the acad.mns file which is located in the
AutoCAD 'support' folder. Using the WordPad text editor, add the two lines
starting with ID_PointXcom and ID_PointYcom as detailed below. I find these two
additions to be absolutely invaluable as they save drawing and erasing temporary
By way of explanation:
Start drawing a line from any point.
Invoke the Osnap menu (shift right click on my computer).
Select 'X of...' or 'Y of...' as required.
The Osnap menu is redisplayed.
You then pick from any of the traditional object snaps (end, mid, int, cen
You then pick on the required entity and the line is completed from its start
location to the X or Y component of the selected entity.
The above may sound a bit cumbersome but it works very easily and smoothly. Give
it a try...
(I have since been told that you can use something called 'tracking' to achieve
the same function. I haven't tried this because I find it hard to imagine that
it would be any easier.)
PS - You may notice I have also added 'Mid-way' to the POP0 menu. I stole this
from the Autodesk site. Very handy for drawing a line from and/or to a point
midway between two other points.
