Which command is used to create a block definition from selected objects in AutoCAD?
Answer: BLOCK
The BLOCK command opens the Block Definition dialog box where you define a name, base point, and select objects to create an internal block.
What is the primary purpose of the WBLOCK command in AutoCAD?
Answer: Writes a block or objects to a separate external DWG file
WBLOCK (Write Block) exports a block definition or selected objects to a standalone DWG file that can be shared or inserted into other drawings.
When you attach an external reference (Xref) using the ATTACH option, how does the Xref appear in the host drawing?
Answer: As a linked reference that updates when the source file changes
An attached Xref maintains a live link to the source DWG file, so any saved changes to the source are reflected when the host drawing is opened or reloaded.
Which XREF option permanently incorporates the referenced drawing's geometry into the host drawing?
Answer: Bind
The Bind option converts the Xref into a permanent block definition within the host drawing, removing the dependency on the external file.
In AutoCAD, what distinguishes an 'Overlay' Xref from an 'Attach' Xref?
Answer: Overlay Xrefs are not included when the host file is itself referenced by another drawing
An Overlay Xref is excluded from the nesting chain, meaning it will not appear when the host drawing is referenced into a third drawing, preventing circular or deep nesting.
Which system variable controls the default path type (absolute, relative, or no path) saved when attaching an Xref?
Answer: REFPATHTYPE
REFPATHTYPE sets the default reference path type: 0 = full path, 1 = relative path, 2 = no path, affecting how AutoCAD locates the Xref when the host drawing is moved.
