Creates a 3D solid from an object that encloses an area, or a 3D surface from an object with open ends.
Mode:
Controls whether the extruded object is a solid or a surface.
Surfaces are extruded as either NURBS surfaces or procedural surfaces, depending on the SURFACEMODELINGMODE system variable.
Height of extrusion:
Extrudes selected objects along the positive or negative Z axis. The direction is based on the UCS that was current when the object was created, or (for multiple selections) on the original UCS of the most recently created object.
Direction:
Specifies the length and direction of the extrusion with two specified points. (The direction cannot be parallel to the plane of the sweep curve created by the extrusion.)
Path:
Specifies the extrusion path based on a selected object. The path is moved to the centroid of the profile. Then the profile of the selected object is extruded along the chosen path to create solids or surfaces.
Blocks and Purge- Autocad 2016 tutorials for beginners Part 30-30. Step by step tutorials for beginners.
BLOCK:
A block is essentially a block definition that includes the block name, the block geometry, the location of the base point to be used for aligning the block when you insert it, and any associated attribute data. You can define a block from drawing geometry either in the Block Definition dialog box or by using the Block Editor. Once the block definition is created, you can reference it in the same or a different drawing.
You can create drawing files for the purpose of inserting them into other drawings as blocks. Individual drawing files are easy to create and manage as the source of block definitions. Collections of symbols can be stored as individual drawing files and grouped in folders.
PURGE:
Removes unused named objects, such as block definitions and layers, from the drawing using the command line.
Removes unused named objects from a drawing at the Command prompt. You can only remove one level of reference at a time. Repeat the command until there are no unreferenced, named objects.
Note: The PURGE command will not remove unnamed objects (zero-length geometry or empty text and mtext objects) from blocks or locked layers.
ou can specify what types of named objects that you want to remove, including blocks, detail view styles, dimension styles, groups, layers, linetypes, materials, multileader styles, plot styles, shapes, text styles, multiline styles, section view styles, table styles, visual styles, registered applications, zero-length geometry, empty text objects, and obsolete DGN linestyle data, or all of these.

Layers Autocad 2016 tutorials for beginners Part 29 30:
LAYER (Command)
Manages layers and layer properties.
Use layers to control the visibility of objects and to assign properties such as color and linetype. Objects on a layer normally assume the properties of that layer. However, you can override any layer property of an object. For example, if an object’s color property is set to BYLAYER, the object displays the color of that layer. If the object’s color is set to Red, the object displays as red, regardless of the color assigned to that layer.
If you enter -LAYER at the Command prompt, options are displayed.
Layers are the primary method for organizing the objects in a drawing by function or purpose. Layers can reduce the visual complexity of a drawing and improve display performance by hiding information that you don’t need to see at the moment.
Before you start drawing, create a set of layers that are useful to your work. In a house plan, you might create layers for the foundation, floor plan, doors, fixtures, electrical, and so on.

In this video we will learn about the 'explode' command in autocad 2016. This command is using for exploding a complex object into its basic elements such as line,arc, polyline etc. If you have an associated array object, you can use this command to explode that also.
EXPLODE (Command):
Breaks a compound object into its component objects.
Explodes a compound object when you want to modify its components separately. Objects that can be exploded include blocks, polylines, and regions, among others.
The color, linetype, and lineweight of any exploded object might change. Other results differ depending on the type of compound object you're exploding. See the following list of objects that can be exploded and the results for each.
To explode objects and change their properties at the same time, use XPLODE.
NOTE:If you're using a script or an ObjectARX® function, you can explode only one object at a time. (Not applicable to AutoCAD LT.)
Here are the results of EXPLODE for each of the following types of objects:
2D Polyline:
Discards any associated width or tangent information. For wide polylines, the resulting lines and arcs are placed along the center of the polyline.
3D Polyline:
Explodes into line segments. Any linetype assigned to the 3D polyline is applied to each resulting line segment.
3D Solid:
Explodes planar faces into regions.
Nonplanar faces explode into surfaces. (Not applicable to AutoCAD LT.)
Annotative Objects:
Explodes the current scale representation into its constituent parts which are no longer annotative. Other scale representations are removed.
Arc:
If within a nonuniformly scaled block, explodes into elliptical arcs.
Array:
Explodes an associative array into copies of the original objects.
Block:
Removes one grouping level at a time. If a block contains a polyline or a nested block, exploding the block exposes the polyline or nested block object, which must then be exploded to expose its individual objects.
Blocks with equal X, Y, and Z scales explode into their component objects. Blocks with unequal X, Y, and Z scales (nonuniformly scaled blocks) might explode into unexpected objects.
When nonuniformly scaled blocks contain objects that cannot be exploded, they are collected into an anonymous block (named with a “*E” prefix) and referenced with the nonuniform scaling. If all the objects in such a block cannot be exploded, the selected block reference will not be exploded. Body, 3D Solid, and Region entities in a nonuniformly scaled block cannot be exploded. (Not available in AutoCAD LT.)
Exploding a block that contains attributes deletes the attribute values and redisplays the attribute definitions.
Blocks inserted with external references (xrefs) and their dependent blocks cannot be exploded.
Blocks insert with MINSERT cannot be exploded. (MINSERT is not available in AutoCAD LT.)
In this video we will learn to use the Erase command in autocad 2016. This command is using to erase the selected objects in a drawing. You can select objects and press delete button on keyboard also. By using this command, you can delete the objects just by clicking on the desired object.
You can erase selected objects from the drawing. This method does not move objects to the Clipboard, where they can then be pasted to another location.
If you are working with 3D objects, you can also erase subobjects such as faces, meshes, and vertices. (Not applicable to AutoCAD LT.)
Instead of selecting objects to erase, you can enter an option, such as L to erase the last object drawn, p to erase the previous selection set, or ALL to erase all objects. You can also enter ? to get a list of all options.

Path Array: Autocad 2016 tutorials for beginners Part 22.
Step by step autocad 2016 basic tutorials for beginners. Subscribe this channel for more related videos.
In this video we will learn to use the 'path array' command in autocad 2016. This is using to array an object over a path that we select. You can change the angle, spacing, number of raws etc in your path array. You can use the associative option to get more editing options in the array.
For more details, watch this video: https://youtu.be/FvqcUrH4BwM . These commands are almost similar in all new versions of autocad.
Arraypath:
Evenly distributes object copies along a path or a portion of a path.
The path can be a line, polyline, 3D polyline, spline, helix, arc, circle, or ellipse.
3D path array:
This command is equivalent to the Path option in ARRAY.
Select objects:
Select the objects to use in the array.
Path curve:
Specifies the object to use for the path of the array. Select a line, polyline, 3D polyline, spline, helix, arc, circle, or ellipse.
Associative:
Specifies whether an arrayed object is created or whether the unassociated copies of the selected object are created.
Yes:
Creates array items in a single array object, similar to a block. With an associative array, you can quickly propagate changes throughout the array by editing the properties and source objects.
No:
Creates array items as independent objects. Changes to one item do not affect the other items.
Method:
Controls how to distribute items along the path.
Divide:
Distributes a specified number of items evenly along the length of the path.
Measure:
Distributes items along the path at specified intervals.
Base point:
Defines the base point of the array. Items in path arrays are positioned relative to the base point.
Base point:
Specifies a base point for positioning the items in the array relative to the start of the path curve.
Key point:
For associative arrays, specifies a valid constraint (or key point) on the source objects to align with the path. If you edit the source objects or path of the resulting array, the base point of the array remains coincident with the key point of the source objects.
Tangent direction:
Specifies how the arrayed items are aligned relative to the starting direction of the path.
2 points:
Specifies two points that represent the tangency of the arrayed items relative to the path. The vector of the two points establishes the tangency of the first item in the array. The Align Items setting controls whether the other items in the array maintain a tangent or parallel orientation.
Normal:
Orients the Z direction of the first item with the starting direction of the path curve.
Polar Array Autocad 2016 tutorials for beginners Part 21.
https://youtu.be/D2AZ9VzbUas Step by step autocad 2016 basic tutorials for beginners. Subscribe this channel for more related videos.
In this video we will learn about the use of 'polar array' command in autocad 2016. This command is using for arranging an object in a polar manner based on a base point. You can use the associative option on/off to get more options. When you use the polar array command with associative option 'ON', the arrayed objects will be grouped as a single object. If you want to edit the array you can use the ribbon panel for the array command. You can change the object count, spacing between the objects etc in this settings.
If you are using the polar array command with associative 'OFF', you can separately select and change the objects in the array.
For more details, watch this video: https://youtu.be/D2AZ9VzbUas
