Do Things by Layer: Used to Move, Copy, Erase or use certain Other AutoCAD commands by Layer. Pick the drawing entity with the layer you want to edit. With a window, pick all other entities you want to edit. Only those entities within the first layer picked will be selected.

Do Things by Block: Used to Move, Copy, Erase or use certain Other AutoCAD commands by Block. Pick the drawing entity with the block you want to edit. With a window, pick all other entities you want to edit. Only those entities that are the same as the first block picked will be selected. An example of a block is a hanger tag.

Attribute

Auto Edit: Select the attributes to change with a window. Enter the existing string to change. Enter the new string to replace the existing attribute string.

Find: The AutoCAD Find command. Opens the Find and Replace dialog box for block attributes.

Move Attribute: Used to move attributes, one at a time, such as a pipe diameter or length or a hanger. Command continues until you right click. This is the same command as Move one Pipe Size/Hanger.

Rotate Attribute: Used to rotate an attribute such as a pipe diameter or a hanger tag.

Swap Pipe Attribute: Select cut lengths or center lengths to swap. Pick one or a multiple of pipe dimensions. The length will be moved to the top of the pipe, and the diameter will be moved to the bottom of the pipe.

Add Prefix to Pipe Size is used to add text or remove it from the front of the pipe size. For example, the f sign is generated by entering %%C in the Prefix box.

Hide Attributes is used to turn OFF or ON the attributes of pipe and hanger lengths, pipe diameters, hanger numbers, or riser nipples.

Use the radio button to Hide or Unhide. Especially useful for pre-submittal drawings.

Change Attribute Properties will open a dialog box where you can select the property to change.

Press OK and select the attribute to change such as a pipe size tag. You will be prompted for the new value.

Attributes to Text will change a block into text on the TEXT layer.

Blocks

Change/Scale/Rotate Blocks:

Opens the Change/Scale dialog box.

Select an Action radio button.

Change will substitute one block into another. For example, you could change head symbols. Select a Typical block to change and Select New will be the new type.

Scale will change the size of a selected block.

Rotate will change the angle of a selected block.

Change Circle will replace circles of a given size and layer with a selected block. You can use this to replace head circles provided by architects with HydraCAD sprinkler heads.

Do all occurrences will be applied to all drawing blocks.

Count Blocks: Pick a typical block. HydraCAD returns the number of identical blocks on the drawing such as a sprinkler.

Remove Blocks: Pick a typical block then pick all similar to remove with a window. The pipes that formerly lead to these blocks will be joined. This is the same as the Remove Blocks command on the Couplings toolbar.

Check Block Layer: Returns the layer of a picked block and gives you the option of changing all other blocks with that name to the layer of the block that was picked.
