# Scale on Y axis only

I have just finishead a drawing of a boat for my local model shop, at the same time they had someone making the fibreglass hull. Just for a change the guy who made the hull has changed the height & width from the origional drawing. What i want to know is if there a way of scaling my drawing on the y axis only, i need to keep the length the same but increase the width by approx 35mm & reduce the height by approx 50mm.

Save your dwg as a block. When inserting you can scale just the Y.

You talk about 3 dimensions, not 2.

Only way I know to scale an object differently in 3 dimensions is what was already suggested. Insert it as a block, set the XYZ scale factors as desired, then explode the block.

Ooops! I missed the 3d discussion.

More precise if inserted as a block and then scaled on the Y-axis using properties dialogue.

I have a couple of "blocking" blocks that I use that are ¼ and ½ inch "thick" by 6 inches on the x-Axis. I insert one or the other then modify the X-scale factor the fit the width.

Same principle as what was suggested.....

I guess you can explode if you want but why add all that crap to the size of the drawing? Earlier versions wouldn't allow exploding if the scale factors were different.... a built-in blessing IMO.

I'm not in favor of exploding normal "blocks" either, as one of their advantages is in reducing file size when there are multiple cases of the block in a drawing. In terms of file size, there's actually a disadvantage in having a single instance of a block present in a drawing, although there may be other reasons than file size for making the item a block.

However, this isn't a "block" question, it's a case of how to transform an entire drawing of a boat -- I assume a 3D model -- in a fairly radical way. The length will remain the same, but the height is slightly reduced and the width is slightly increased.

This could probably be done manually, eventually, but it would be much faster and easier to insert the original drawing into a new one (as a block) then adjust whichever of the XYZ scale factors need adjustment. I'd probably scale by "reference" to achieve the desired dimensions. Somewhat similar to your blocking blocks, except with another dimension in play.

Then I would certainly explode the block, and purge the block definition. Remember, the object here is to edit a whole drawing, not to create or maintain a block of any kind. After purging the unused block, the new drawing will be exactly the size of the original, except it will be miraculously transformed to the desired dimensions. The only point of a block in this whole discussion is as a temporary working method to achieve the final product.

If we didn't have the ability to explode a nonuniform block, then we'de be condemned to doing all of this in a much harder way, and we'd probably wind up stuck with a bloated and unworkable drawing -- namely, one that consists entirely of a single instance of an unexplodable block.

Hoe did you cope BEFORE you had a program that allowed exploding of non-uniformly scaled blocks.

I agree with your reasons for exploding....wasn't thinking of blocks on that level of magnitude. (Don't let maddcad know that I actually am in favor of exploding inserted blocks on certain occasions....)

Without the ability to explode, I guess in a case like this I would have traced over the nonuniform block & then erased it. The sticky part, in this example, is that arcs might become partial ellipses, or whatever. You'd probably have to appproximate any curves using splines.

teiarch, teiarch, teiarch, just what am I to do with you?

Too late, I know now, but now I have to give you yet another lesson. At least as far as 2006 goes, can't speak for 2007.

You can insert a block non-uniformly and explode it ONLY if that block is NOT a solid. If it is a solid, it will not allow exploding just like the "good ol' days" that you are so fond of.

That's right, if it is a solid that is the block, you can either insert it non-uniformly or change it after insertion in the property box to be non-uniform (that's other than 1.00 in X, Y or Z) and it will be unexplodable. Knowing that, you may want too make all your blocks that way.

No one but you cares whether I like to explode blocks. Really, I don't care so it's just you.

Your feeble rantings further confirm to all who read them that if it weren't for the internet, you probably wouldn't experience any social intercourse at all.
