## Lesson81- Copying Hatch Properties

You can copy the properties of an existing HATCH object using two different methods. if you are creating a new HATCH object you can use the Inherit  Properties feature in the Boundary Hatch dialogue box. if you are updating an existing HATCH object you can use the  Matchprop command. both methods help to create consistent HATCH objects in your  drawings without having to know much about these properties. To use the Inherit Properties approach you can use the Bhatch command Read More...

## Lesson80- Hatch Properties

Scale HATCH objects are created in the Model so you must take the drawing scale into account when you specify a hatch scale. If the drawing scale is 1:1 then a hatch scale of 1 should create HATCH objects at a reasonable scale for drawings in inches or mm. enlarge the model when you Plot (e.g. 4:1 drawing scale) and you must reduce the hatch scale proportionately (e.g. 0.25). reduce the model when you Plot (e.g. 1:10) and you must increase the hatch Read More...

## Lesson79- Crosshatching Overview

You can create HATCH objects to automatically fill 2D areas with various hatch patterns. the most common application involves section views where different hatch patterns represent different parts or materials. Use the Bhatch command to invoke the Boundary Hatch dialogue box for creating new HATCH objects. Defining The Boundary Valid 2D boundary objects include LINEs, ARCs, CIRCLEs, LWPOLYLINEs, SPLINEs, TEXT and MTEXT. You can specify a hatch boundary in two different ways. select objects manually but each boundary object must meet  (exactly) end-to-end or there Read More...

## Lesson78- Editing Dimensions

There are many ways to edit existing dimensions & the method you choose will depend on the type of change & number of dimensions. You can use Stretch on dimensions and the dimension text will update automatically (unless you replaced <> with text). You can also use grip editing techniques to stretch grips of dimension objects for various different effects. select a dimension if no command is running to display grips. left-click on a grip to make it hot and then Read More...

## Lesson77- Using Styles In Other Drawings

You should include all dimension styles that you plan to use regularly in your custom template files so when you begin New drawings from a template these dimension styles are readily available in the current drawing. If the desired dimension style is not saved in the current drawing there are two easy ways to import styles from another drawing. if the source drawing (the one with the desired style) is open you can use the Matchprop command. you can also use AutoCAD DesignCenter Read More...

## Lesson76- Dimension Styles & Drawing Scale

Dimension variables are special system variables stored with each  drawing to control the appearance of dimensions. a dimension style is a collection of dimension variable  settings that you save with a unique name in a drawing. you can completely change the way dimensions appear by  changing variable settings in a dimension style. Use dimension styles to standardize dimensions and conform to a  particular drafting standard or office preferences. Save your custom dimension styles in your custom template files so Read More...

You can use leaders to add notes (annotations) that point to specific objects in your drawing. this can create an MTEXT object (annotation) & another object that points to the desired area of the drawing (lines & arrows). You can change settings by right-clicking in the drawing area at the first Qleader prompt & selecting Settings from the shortcut. changes made to Settings are saved in your drawing so you can have different settings in different drawings. Reduce the amount of clicking required Read More...

## Lesson74- Quick Dimensions

AutoCAD 2000 introduces a quick way to make multiple dimensions in one operation with the new Qdim command. Qdim may not replace other commands to create dimensions in production drawings but it can save time in some situations. You select geometry and AutoCAD acquires key points of the selected geometry (such as endpoints and center points). these points are used as origin points for the new dimensions. You can right-click to invoke a shortcut menu to select the type of dimensions that you Read More...

## Lesson72- Angular Dimensions

Most angular dimensions involve angles formed by 2 LINE objects. use Dimangular to create this type of dimension. select the 2 LINEs. then pick a point for the dimension line arc location. AutoCAD uses the point you pick for the dimension line arc location to decide which of the four possible angles to dimension. the examples below show how the same 2 LINEs could be used to generate four different angular dimensions. If you press <enter> at the first Dimangular prompt (instead of selecting a Read More...

## Lesson71- Ordinate Dimensions

Ordinate dimensions can be used as an alternative to linear dimensions (often used to dimension CNC machined parts). X ordinates are labeled along the top or bottom Y ordinates are labeled along the left or right side. create this type of dimension using Dimordinate. Leader lines can be straight or “dog legged” to clear obstructions in the drawing if required or to spread out dimensions that would be too close together if the leader lines were straight. Ordinate dimensions are relative to the current UCS Read More...

## Lesson70- Dimensions For Distance

Dimension origins are created as definition points (defpoints for  short) on a special Layer called DefPoints. objects on the DefPoints layer are visible on-screen but this layer  is automatically defined not to appear when you Plot. definition points are very small and usually lie on objects being  dimensioned so you may not even notice them on your screen. Dimensions relating to distance require two types of information. you must supply defpoints as origin points & you must also specify (or imply) a direction Read More...

## Lesson69- Using Attributes In Title Blocks

When you use a title block in a new drawing you must enter variable data according to the current drawing file. for example, you will probably want to record the current drawing file name in a box labeled as ACAD FILE. One approach is to leave these title block boxes empty & fill them in  after you insert the title block drawing into a new drawing file. this approach demands extra work in placing the text at the  correct locations Read More...

## Lesson68- Introduction To External Reference Files

Attaching a reference file to the host (active) drawing with Xref is like using Insert to insert that drawing file except the current version of the reference file is reloaded into  the host every time you Open the host. whereas after you Insert a drawing file into another drawing the  original file that was inserted is no longer used or required. You can use reference files in any assembly drawing (host) that  references component drawing files (xrefs). changes to Read More...

## Lesson67- Introduction To AutoCAD DesignCenter

AutoCAD DesignCenter is a tool to find, access and re-use content that is not already stored in an open drawing. obvious content types include drawings & block definitions but content can have many other forms (including content  created by custom applications). Selected content can be dragged into an open drawing without having to open the drawing file where this data is stored. for example, you could preview selected block definitions stored in any closed (or open) drawing file. then Read More...

## Lesson66- Drag & Drop Cut & Paste

Drag & Drop (objects) In AutoCAD 2000 (first version to support the Windows Multiple Document Interface) it is easy to re-use objects in other drawings. One approach is to drag & drop object copies from one (open)  drawing file into another (open) drawing file. Tile drawings in their own individual windows so you can see  both drawings of interest at the same time. select source objects when no command is running. press & hold your right mouse button and drag Read More...

## Lesson65- Inserting Blocks & Drawing Files

You can Insert block definitions or drawings into the active drawing. select one of the defined blocks in the current drawing from the drop-down list. you can also pick Browse to select a drawing file to insert and this will create a new block definition in the current drawing. There are three main parameters for Insert. Insertion point corresponds to the base point that was specified  when the block was defined. Scale is relative to the original objects selected when the block Read More...
