AutoCAD 2D for beginners

Lesson64- Making Block Definitions

You can easily create new block definitions with Bmake. begin by typing a Name for the new block definition that is unique in the current drawing. then pick the Select objects button and use selection tools to select objects for the block. pick the Pick point button and use osnaps to select an appropriate base point relative to the selected objects. the block definition is stored in the current drawing file. Blocks & drawing files can have insert units Read More...

Lesson63- Introduction To Blocks

Objectives: Understand What Blocks Are & Where They Are Stored Learn How To Define Blocks With BMAKE Learn How To Insert Blocks & Drawing Files Using INSERT Drag & Drop Cut & Paste AutoCAD DesignCenter Introduce Attributes Creating Custom Title Blocks With Attributes Editing Attribute Values In Blocks Introduce Reference Files Learn How To Use XREF To Attach A Reference File Understand The Difference Between INSERT & XREF What Are Blocks? A block definition is a named imprint for a selection set of objects. when this imprint is stored in the current drawing Read More...

Lesson62- Spell Checking

Use the Spell command to verify whether or not selected objects contain text that is spelled correctly (as per the current dictionary). if you use spell checking in other Windows applications you should already be familiar with the Spell Checking dialogue box. You are prompted to select objects to check. all objects in the Model tab as well as the last active Layout tab are checked if you enter ALL at the Select objects prompt. AutoCAD ignores objects that were not created as Read More...

Lesson61- Using Find & Replace

Use the Find command to find & replace text in drawings. text can be in block attribute values, dimension annotations, 
hyperlinks, hyperlink descriptions as well as TEXT & MTEXT. you can restrict your search to selected objects or apply the 
search to an entire drawing file. You can use this tool to merely Find text and then use the Zoom to 
button to display the drawing area where this text is found or you can actually Replace any or all found occurrences. You can Read More...

Lesson60- Editing Existing Text

You can explicitly edit TEXT objects using ddEdit or you can select one TEXT object then right-click to invoke a shortcut instead. then select Text Edit to change the selected TEXT object in the Edit Text dialogue box. the shortcut will not be available if you select more than one TEXT object. You can also use Properties to edit the text string of selected TEXT objects. you can edit more properties (not just the string) this way such as the Style, Justification, Rotation, Read More...

Lesson59- Introduction To Multiline MTEXT Objects

You can create entire paragraphs (multi lines) of text as a single MTEXT object and each character can be formatted separately. use the Mtext command to create MTEXT objects.
Mtext lets you format characters individually using familiar Windows techniques in the Multiline Text Editor. select the desired text in the editor & select the desired format from the Character tab to change the selected characters. You can change settings for an entire MTEXT object from the Properties and Line Spacing tabs Read More...

Lesson58- Creating & Modifying Text Styles

Text styles control the appearance of TEXT objects using the parameters that you assign for the selected Font & desired Effects. AutoCAD uses the current text style when you create new TEXT 
objects with Dtext. invoke the Style option of Dtext to select a different text style for 
new TEXT objects (this becomes the current style as well). you can also invoke the Style command & select the desired 
style in the Text Style dialogue box to change the Read More...

Lesson57- Single Line TEXT Objects

Use Dtext to create individual lines of TEXT objects. you can create multiple lines using this approach but each line 
of text is a separate TEXT object (unrelated to the other lines). for example, the four individual TEXT objects shown below could 
be created using the command line history shown. Command: DTEXT↵ Current text style: "Standard" Text height: 0.2000 Specify start point of text or [Justify/Style]: (pick P1) Specify height <0.2000>: 1 ↵ Specify rotation angle of text <0>: ↵ Enter text: DTEXTMAKES↵
Enter text: SINGLE Read More...

Lesson56- More Practice TRACKING

Open the T109_5.dwg in your personal folder and create the boundary LINEs for the missing section view as shown. use tracking techniques ONLY. do NOT use construction lines do NOT use Fillet, Offset or Trim commands. hatching is not required. Open the T109_6.dwg in your personal folder and create the missing top view as shown. use tracking techniques ONLY & use appropriate layers. Open the T109_7.dwg drawing in your personal folder and complete the side, auxiliary & profile views as shown below. there is sufficient information in Read More...

Lesson55- Tracking With Parallel & Extension Osnaps

You can track using the Parallel osnap tool. acquire Alignment points using the Parallel osnap and you constrain the tracking vector parallel to the segment of interest. the Parallel osnap can avoid having to define a temporary UCS or create temporary construction objects (e.g. avoid Offset). The Extension osnap lets you track along the extension of an existing object (even non-linear objects like ARCs). this can avoid having to create temporary construction objects (e.g. Lengthen existing LINEs) just to find the desired point. for Read More...

Lesson54- Temporary Tracking Points

OTRACK uses running osnaps as alignment points for tracking when the OSNAP status bar button is On you can also specify temporary tracking points manually and they do not have to reside on an object snap point.   you can type TT at the keyboard or pick the Temporary Tracking Point button to use temporary tracking points. One way to use temporary tracking points is as an alternative to using the From tool. for example, you could create a CIRCLE (hole) that is 0.5 Read More...

Lesson53- Automatic Object Snap Tracking

You can create temporary LINEs as construction objects when you draw in AutoCAD. for example, you can transfer features between views by creating LINEs and then using Trim to make them the correct length. The Object Snap Tracking feature lets you create the desired objects directly without having to perform secondary operations. you can make drawings with less effort if you take a moment to master the basics of Object Snap (Automatic) Tracking. Object Snap Tracking is in Read More...

Lesson52- More Practice

Jig.dwg Create the three drawing views for the tool illustrated below. start from scratch using English defaults. create appropriate layers and save the drawing as Jig.dwg in your personal folder. Floor plan.dwg Create the floor plan illustrated below. start from scratch using English defaults create appropriate layers and use Architectural units. save this drawing as Floor plan.dwg in your personal folder.   Read More...

Lesson51- Orthographic Views & Construction Lines

Drafting tools in AutoCAD 2000 make it easy to create 2 dimensional orthographic views that are properly aligned. 
the most important tool for orthographic views is POLAR. You normally start a drawing by creating 1 or 2 orthographic views. when you add a feature in one view you can update the other view to reflect the new feature. For example, you might begin the drawing of a V block by creating the end view first because it has the most information. Read More...

Lesson50- STRETCH command

You can combine the effects of Move & Extend or Trim in a single operation to Stretch existing designs into new shapes. you must use a Crossing or CPolygon tool to select objects for Stretch to function properly. If an object is entirely inside the selection box then the entire object is Moved by the specified displacement. you can actually use Stretch in place of Move if you select the desired objects to move using a Crossing or CPolygon tool. If endpoints of LINEs & Read More...

Lesson49- MIRROR command

Most designs are symmetrical in some way and you can save CAD construction time if you recognize this symmetry. use Mirror to automatically generate symmetrical features after you create the original features. this can save time & avoid potential errors that could be introduced by re-creating the symmetrical geometry manually. Delete Source Objects You can use Mirror to convert left side parts to right side parts or Mirror house/building plans to generate alternative designs. 
when you use the Mirror command to generate Read More...

Lesson48- ARRAY command

You can make multiple copies of objects using Copy but when the copies repeat in a regular pattern you can use Array to save time. for example, you could draw the first thread and use Array to automatically make the remaining threads for the screw below. Rectangular A Rectangular Array is a pattern with rows & columns. you can specify the distance between rows (vertically) and the distance between columns (horizontally). Distances can be positive or negative. positive distances correspond to the positive direction of the Read More...
