What happens to blocks when the Scale uniformly option is selected in the Block Definition dialog?

1. They cannot have different X and Y scales.

2. They become grouped automatically.

3. They are locked to prevent further scaling.

4. They lose their current dimension properties.

The correct answer is: They cannot have different X and Y scales.

When the Scale uniformly option is selected in the Block Definition dialog, the key outcome is that blocks will maintain proportional scaling for both the X and Y axes. This means that any scaling applied will occur uniformly, ensuring that the aspect ratio of the block remains intact. As a result, the blocks cannot have different X and Y scales; any scale factor applied will affect both axes equally. This uniform scaling is particularly useful in maintaining the integrity of the block’s design, making it vital for preserving the visual and functional properties of the block when resizing. If blocks were allowed to scale differently along each axis, it could lead to distortion of the block, which is generally undesirable in design and drafting applications. Therefore, the importance of consistency in scaling through this option underlines why maintaining the same scale for both dimensions is essential in CAD practices.
