stretch does not move blocks

[carlosvidal]

Hello,

I`ve a problem when i`m using the stretch commend, for istance to move the position of a wall opening done with a poliline and there`s a door or a window block within the stretch area, this object stays in the original position whereas the lines has already been streched. This makes that I`ve to move manually the block to the new position. Is there any way to stretch objects and blocks together?

I use no geometric costriants and i do have the whole block selected when trying to stretch. Any suggestion about what could be the cause?

I enclose a sample where the prblem occurs (doors are blocks)

Thanks

Hi,
I can not test your DWG just now, but can you check that you hook the insertion point of the block you try to stretch - it is critical point in streching (moving) blocks.

Yes, I was right - insertion point of blocks in your drawing is far away from block geometry itself.

Hi, thanks for your answer. How do you set a new insertion point in Autocad 2012 for mac? 

Editing the block I haven`t found out the way to change that...

Thanks!

You can change insertion point of the block in AC 2012 for Mac the same way as in AC for Windows:

1. In block editor: move all block data to the WCS origin point (0,0,0), this point in block editor is actually the insertion point for the block you edit

2. Redefine block by exploding it and recreating after with new insertion point

3. Using "In-place" block editing feature: move all block data to it's current insertion pint and save changes.

When you are moving block date you can use as base point for move operation the point that you want to be insertion point.

But also keep in mind, that after changing insertion point of the block definition all of already inserted blocks will "jump" to the new position in drawing, so you have to move them manually back to old position.

I think it is possible to write Lisp routine to automate this operation (redefinition of insertion point without loosing current position(s) of inserted block(s).

And one more thing;

If you redefine insertion point of the block with attributes, you have to use ATTSYNC command to move attributes to right position relative to block entities.

Thank you very much. This last  command yo wrote was jut the thing I was trying to find out!

Check Lee Mac's web page.

He has a LISP to change your Block Base Point w/wo retaining reference position

EDIT:

Just tryied it out and it didn't worked on my case. Need to edit all the blocks manually. Bummer!

AutoLISP routine from Lee Mac's site uses Visual Lisp functions which are not available in AutoCAD for Mac, so you can not use this routine in AC for Mac.

hi

does auto cad for mac has a library of standard profiles?
i need hydrofoils!!
