SCALE different in x and y direction


Recommended Posts

I can't believe that in Acad 2006 there's no way to scale an object in one direction only e.g.

in x direction scale = 1.15, in y direction scale unchanged i.e 1.0.

Mstation does it - surely there must be at least a workaround in Acad?

In addition to what Dadgad said, if you are looking to scale 3D solids by this method, then please pay attention the resulted block cannot be exploded, therefore will not be able to use further the entities.

Dadgads suggestion works like a charm, but if you don't need to have whatever you need scaled as it's own DWG, its enough to just use the command BLOCK which only creates a block-definition inside the drawing.

 

AutoCAD Mechanical has a command that does this built in and yes, it's annoying that it's not in vanilla autocad.

Wow I never knew about WBLOCK, only BLOCK, which I use a lot. Is the only difference that WBLOCK is stored as a separate .dwg, everything else the same?

 

But - I can't see how to scale either a BLOCK or a WBLOCK along one axis - I just get offered the same SCALE command without choice of axis.

I can't see how to scale either a BLOCK or a WBLOCK along one axis

You can do that either in Properties, if the block is already insterted, or at insertion time.

Great, I've never dabbled in this.

But I want to scale my object on an axis that is 45o to the y axis - e.g. a square gets stretched from bott R to top L, but no distances get stretched from bott L to top R, so the square goes kite-shaped. I have tried rotating the square 45o before WBLOCKing, so that as WBLOCKed the y axis is indeed the one I want to stretch - but the stretch still happens to the original y-axis, so the square just goes rectangular.

Welcome to the forum. :)

I don't see why you cannot use the EXPLODE command,

Depending of course on your geometry.

What types of drawing entities are there in the drawing, which you would need to block?

Can't you use PEDIT or similar commands after exploding the block?

Can you upload the drawing, or a representative sample of it?

 

Hmmm, I just saw Mircea's note in the earlier post.

Can you post something as a test?

Sort of like this?

As previously described, I used the WBLOCK command

with Convert option, to change it into a block.

Once it was a block I changed the SCALE X Factorfrom 1 to 1.35 in the QUICK PROPERTIES palette.

Then I EXPLODED the block into LINES, which I JOINED with the PEDIT command

Multiple option, which made them all POLYLINES again.

I am not sure what sort of entities you need them to be for your CNC process.

Then I used the PEDIT command again with the Spline option which

converted them to 2D Polylines.

I am guessing that one of those entity types must be compatible. :)

ScaleXYZ - scales selected objects independently in the X-Y-Z axis (VLX Lisp for AutoCAD) is available at the CADforum under Downloads > CAD Freeware > CAD Utilities.
