How to group objects?

[Murphy625]

I've gotten good at making 3 dimensional drawings but am having difficulty when dealing with overlapping parts.

How do I group a bunch of lines and circles into one object that will move as a group? And then be able to "un-group" them when needed?

Im using AutoCad R14.

Thanks,

You can use "BLOCK", I'm not sure if you can use "GROUP".
Group is better but I don't remember if R14 supports Grouping. It is also possible to use LISP to create your own collections of objects that you can refer to by name.

Yes,

I use blocks, not groups. I have a lisp, that makes a anomymous block of the selected objects. Maybe it works in AC14. Intrest? E-Mail?

The only problem is that I have never used a lisp routine before. I know what they are but have never required one.

I have much to learn with autocad. I think you would be surprised at how much I have done with this program and how little knowledge of its full usefullness I actually have.

You have to search for a tutorial for R14.

Here is one for 2004:

Normally, I would block which circles and lines I want and give the move command. As an alternate suggestion, you could use the Union command to create a single object and use Move command for placement. After placing the object where you want, I would use the Explode command to return the object to circles and lines.

Hope this helps,

I tried the UNION command and it keeps telling me that "only coplaner or solids" can be selected.

I can never get the block command to work right.

There's something about drawing in 3D that autocad does not like. It does it, but things quickly become difficult to manipulate because the software wont let me do to much to an object unless I am in the same drawing plane as the object was drawn in.

Keep the suggestions coming!!! Thanks for the info!!!

You are confusing grouped lines and circles in 3-space with 3D objects. In AutoCAD, they are very different.

To get an idea of how different, use the BOX command and the CYLINDER command. You can do Boolean operations on the resulting objects.

You can also make a 3d object by using the EXTRUDE command on a closed polyline.

You _really_ need to find a copy of "Inside AutoCAD". It will take you farther in a week than you've gone so far. Don't bother with the diskette; do all the examples and make your own.

Thanks..

Im going to look around for Inside Autocad.

I wish this forum would let me respond to replies in a stepped order instead of this list type display.

Ok.. Time to get back to my drawing .. LOL

Thanks again!

grouping is supported in Acad 14,

tools -> object group

give name (if needed)
[new] select objects
[ok]

this will create a group of objects that will move together

only if groups are turned on

tools -> drawing aids -> groups checked = groups on
un-checked = groups off

you can turn off grouping, then move individual objects, then turn grouping back on and move all objects together.

hope this helps
