BLK File Extension

What is BLK file?

BLK files are associated with AutoCAD software package.

What kind of data can BLK files store?

BLK files are used for storing AutoCAD projects. BLK files contain the necessary information for project to be published to DWF, PDF, or DWFX formats. BLK files typically store data in blocks. Beside AutoCAD drawings, BLK files can also store properties of drawings.

What are BLK files used for?

BLK block files are typically used when multiple drawings that differ in only certain parameters must be prepared. Modularity of BLK files allow AutoCAD to efficiently load slightly modified drawings without reloading the whole project.

Limitations regarding project distribution

One other use of BLK files is controlling project data distribution and sharing. Complex projects commonly require only certain parts of the whole project, like specific sections, modules, or project views to be shared among team members. BLK files are ideal for restricting what types of information related to given AutoCAD project should be shared.
