Learning as I go.

I had issues using blocks – when using blocks from one file for another file, the blocks were not coming out the correct scaled size they should in reference to what the blocks were thought to be saved as. I re-defined the blocks and re-exported the blocks (after deleting these exported blocks in the ‘examples’ file) to see if that would overcome the issue. But it didn’t. All other sketch dimensions seem to be the same across both files with corresponding dimensions. Since attempting to alter the saved blocks, the original won’t save unless I ‘save as’ – it states ‘error occurred during the saving’, and it keeps happening when altering another ‘saved as’ version. Has fiddling with the blocks upset some links? How do I rectify this saving issue? And how do I make my saved blocks come up the correct size between files?
