Watch free video tutorials of AutoCAD 2012 in URDU language. The videos start from the basics and right up to the very advanced levels such as AutoCAD raster design, Layouts, Layers, Blocks, Libraries, XRef, Isometric drawing and 3D AutoCAD Tutorials.
Blocks are by basically electronic glues that bind multiple objects together and store them up in the drawing for putting up the same object anywhere else in the drawing. The important thing however is to remember that "BLOCKS ARE A PART OF ONE DRAWING AND WILL NOT BE AVAILABLE (DIRECTLY) IN OTHER DRAWINGS".
You might think that What's the good use of blocks then? Watch tutorials below to find out
This video explains the basic method of creating and editing hatch patterns in AutoCAD 2012 on a simple floor plan of a house. The video shows different textures of hatching and how to scale a pattern and change the angle of a hatch pattern.
Hatching is used to add shaded patterns
to objects and shapes within an Autocad drawing. Hatch patterns
can be used to indicate a material
to be used, such as a concrete hatch. Alternatively it could
be used to make an area of a drawing stand out.
Take a look at the drawing above. You'll see a
complex assembly drawing and two different section views. On the far
left, you see the line that indicates where Section B-B is. On the right
side, you see the section view. Does it make sense to you? What you are
seeing is the cross section view of the metal beam part of the of the
bracket. It's shown so that you can see what size the area is without
having to look at the entire side view of the assembly. Section views
are used for clarity.
Look for the indicators for
Section A-A. Then look at the top right view. You'll see that the beam
part is shown as well as the hole that is drilled through it.
Section views are used in
Mechanical and Architechural drafting. Anytime you need to show some
detail that isn't readily seen from an exterior view, "cut it up" and
draw it.
