How do I move 3D objects perpendicularly using snaps

[brian911]

Often, I want to move a 3d object from a 2D view perpendicularly to the edge of another object. However, if I use snaps, the moved object's Z-coordinate changes. I have a few ways around this. One is using DIST to find the delta distance then use orthogonal move by that amount. Problem with this method is often the distance I want to move is not an easy number and I'm forced to round off so the model is inaccurate. Another method uses lines and the trim function that I won't go into much detail. I'm wondering if there's an easy way to do this?

To move an objects with snaps but perpindicular then use ORTHO. Which wil move it only in the current UCS x-y.

This is a way used in older versions, you can try it:
When you are asked for base point or displacement pick the first point. You are asked for the next point. Enter .Z<enter> on the command line appear of and you answer with the @ sign. You are prompted for the XY cords. Press the destination point.
In this way, the Z coord is preserved.

Thanks, that was exactly what I was looking for.

BTW, you mentioned this method was used on older versions. I use AutoCAD 2004. Is there another or simpler way?

No, Point filters as mentioned above is still the way to move 3d objects in the current version of autocad.

like most things, the more you use it, the easier the concept becomes.

Working with object tracking and with temporary track points sometimes we forget the point filters. This way is usefull just it is not used so often as in the past.
