Multiple copy items by reference point

Question

Hello - still getting used to VW from Autocad. I'm trying to work out how to copy an object multiple times but relative to a given point that its not part of the object to be copied. A bit like a multiple array. I hope that makes sense! All I can make it do is cntrl C / Cntrl V then move using grips which is a bit laborious.

This is something that I had already struggled and still didn't had a solution.

How do I do several copies from an original object without knowing the number of copies? What I would like to do is to copy an object giving a base point and then just click where I want my copied object layed out.

Can someone help me?

Thanks for answering Jonathan, I've had a chance to play with that command and its not quite what I need. I've drawn a diagram that I hope clarifies things (Joao - I believe this is similar to your question too, but what if the 'future' base point was on randomly spaced objects diagram also attached).

 

The move by point command* works when there is an equal spacing between entities. But what I need is a command that will let me copy an object which is 'off grid' from the array, but the base point is the same. Hopefully the diagram clarifies. Its a simple concept, but surprising hard to write down!

 

*(see attached screen shot of the command line for the tool - slight rant alert why is this called 'move' and not 'copy' or 'array'? Copy write with ACAD maybe..........)

 

Thanks in advance

You could try to turn the square into a symbol (Or "block" in  acad terms)

then when you edit the square to add the circle, that will give you the result you're after. Then you can explode the symbols with "convert to group"

Thanks Russ, thats interesting and would work for a simple shape. The problem comes when moving the 'circle' relative to a complex object. A real world example would be a light switch symbol (ie the circle) relative to a door reveal in a number of room locations. The door position in plan would vary (effectively 'randomly'), but the proximity of the light switch to the door reveal would be the same in each location.

 

In Acad the copy command would allow me to select the circle, then select the base point and then click to position A in any location, any amount of times and the object will place relative to A each time. Its quite handy!

Ah, ok, I see where you're going.

 

Well, I frequently have 2d and/or 3d locus in with the geometry. So for your circle example, I would group a 2d locus in there with it, which becomes your ancor or snap point.

Also, have it on it's own unique class, so you can switch it off later. I tend to have a class called somthing like Construction-snaps or similar to do this.

In terms of automating the process, I can't think of a way, but having a locus as a pre-offset "handle" for the object would make life much easier.

 

So either put one in the door, as a "place light here" point, or on the switch as a "corner of door goes here" handle..... or both!

Thanks for this Russ, thats very helpful.

 

I think the issue maybe I'm currently only using VW as a 2d drafting tool and not exploiting its full potential. We've booked in training to get up to speed with BIM and 3D, but until we've done this it seems like work arounds for some commands (like this one) are the order of the day. Thanks for taking the time though Jonathan and Russ.

 

Cheers

Okay, I've found a work around. ctrl C / ctrl V to copy and paste the item to be copied in place (ie an exact duplicate cut and pasted over the original item in the original place so you make a copy), with this duplicate selected, use the 'move by points tool' object retention mode (value set to 1) and you can copy / move relative to a point multipe times.

 

Have a great weekend
