The Region command is used to transform objects into regions rather than actually drawing them i. Once a region is created, there may be little visual difference to the drawing. However, if you set the shade mode to "Flat Shaded", View Shade Flat Shaded , you will see that the region is, in fact, a surface and not simply an outline.
Regions are particularly useful in 3D modeling because they can be extruded. Before starting the Region command, draw a closed shape such as a rectangle, circle or any closed polyline or spline. A Wipeout is an image type object. Most commonly it is used to "mask" part of a drawing for clarity. For example, you may want to add text to a complicated part of a drawing. A Wipeout could be used to mask an area behind some text so that the text can easily be read, as in the example shown on the right.
The Wipeout command can be used for 3 different operations. It can be used to draw a wipeout object, as you might expect, but it can also be used to convert an existing closed polyline into a wipeout and it can be used to control the visibility of wipeout frames. You can use as many points as you wish in order to create the shape you need. When you have picked the last point, use right-click and Enter or hit the Enter key on the keyboard to complete the command and create the wipeout.
You may find that it is easier to draw a polyline first and then convert that polyline into a wipeout. To do this, start the Wipeout command and then Enter to select the default "Polyline" option. Select the polyline when prompted to do so. Remember, polylines must be closed before they can be converted to wipeouts.
The Frames option is used to turn frames off or on for all wipeouts in the current drawing. You cannot control the visibility of wipeout frames individually.
You should also be aware that when frames are turned off, wipeouts cannot be selected. If you need to move or modify a wipeout, you need to have frames turned on. It is often more convenient to draw the wipeout after the text so that you can see how much space you need. Find it on your pull-down at Express Text Text Mask. Points are very simple objects and the process of creating them is also very simple. Points are rarely used as drawing components although there is no reason why they could not be.
They are normally used just as drawing aids in a similar way that Construction Lines and Rays are used. For example, points are automatically created when you use the Measure and Divide commands to set out distances along a line. When adding points to a drawing it is usually desirable to set the point style first because the default style can be difficult to see.
The point command will insert a point marker in your drawing at a position which you pick in the drawing window or at any co-ordinate location which you enter at the keyboard. The default point style is a simple dot, which is often difficult to see but you can change the point style to something more easily visible or elaborate using the point style dialogue box. Points can be used for "setting out" a drawing in addition to construction lines. You can Snap to points using the Node object snap.
See the Object Snap tutorial for details. Strangely, in Multiple Point mode the default for the Point button on the Draw toolbar you will need to use the escape key Esc on your keyboard to end the command. The usual right-click or enter doesn't work. You can start the point style command from the keyboard by typing DDPTYPE or you can start it from the pull-down menu at Format Point Style… The command starts by displaying a dialogue box offering a number of options.
To change the point style, just pick the picture of the style you want and then click the "OK" button.
You will need to use the Regen command, REGEN at the keyboard or View Regen from the pull-down to force any existing points in your drawing to display in the new style. Any new points created after the style has been set will automatically display in the new style. One interesting aspect of points is that their size can be set to an absolute value or relative to the screen size, expressed as a percentage.
The default is for points to display relative to the screen size, which is very useful because it means that points will remain the same size, irrespective of zoom factor. This is particularly convenient when drawings become complex and the drawing process requires a lot of zooming in and out. Multilines are complex lines that consist of between 1 and 16 parallel lines, known as elements. The default multiline style has just two elements but you can create additional styles of an almost endless variety.
The Multiline Style command enables you to create new multiline styles by adding line elements, changing the colour and linetype of elements, adding end caps and the option of displaying as a solid colour. The Multiline command is used to draw multilines. This process of drawing is pretty much the same as drawing polylines, additional line segments are added to the multiline as points are picked. As with polylines, points can be unpicked with the Undo option and multilines can be closed.
When you start the Multiline command you also have the option to specify the Justification, Scale and Style of the multiline. The Justification option allows you to set the justification to "Top", the default, "Zero" or "Bottom". When justification is set to top, the top of the multiline is drawn through the pick points, as in the illustration below. Zero justification draws the centreline of the multiline through the pick points and Bottom draws the bottom line through the pick points.
Justification allows you to control how the multiline is drawn relative to your setting out information. For example, if you are drawing a new road with reference to its centre line, then Zero justification would be appropriate. The Scale option allows you to set a scale factor, which effectively changes the width of the multiline. The default scale factor is set to 1. A value of 2. The Style option enables you to set the current multiline style. The default style is called "Standard".
This is the only style available unless you have previously created a new style with the Multiline Style command. Follow the command sequence below to see how the Multiline command works and then try changing the Justification and Scale options.
The Multiline style command is used to create new multiline styles, which can then be used with the Multiline command. When you start the command for the first time, you will see the Multiline Styles dialogue box indicating that the Standard style is "Current".
The dialogue box should now look something like the one on the right. When you are happy with the new name and description, simply click on the "Add" button. Your new style will now appear in the "Current" box. The new style you have created is simply a copy of the Standard style, so the next step is to change the style to suit your own purposes. Click on the "Element Properties…" button to proceed. You will now see the Element Properties dialogue box appear.
This dialogue box allows you to add new line elements or delete existing ones and to control the element offset, colour and linetype. Click the "Add" button to add a new element. A new line element now appears with an offset of 0. Highlight the top element in the "Elements" list and change the offset to 1.
Now do the same with the bottom element remembering to enter a value of You now have a multiline that is 2 drawing units wide with a centre line. Let's now change the colour and linetype of the centre line. Highlight the 0. To change the colour, simply click on the Colour… button and select an appropriate colour from the palette.
When a colour has been selected, click the "OK" button on the palette to return to the Element Properties dialogue box. Changing the linetype is a little more complicated because we will need to load the required linetype first. However, click on the "Linetype…" button to proceed. Click on the "Load…" button. The Load or Reload Linetypes dialogue box now appears. Scroll down the list of linetypes until you find one called "Hidden".
Highlight Hidden and then click the "OK" button. You will now see the Hidden linetype appear in the "Loaded linetypes" list in the Select Linetype dialogue box, which should now look similar to the one shown above. Finally, highlight Hidden and click the "OK" button. Your Element Properties dialogue box should now look similar to the one in the illustration above.
To complete our new style, we will add some end caps and a solid fill. Click on the "Multiline Properties…" button to proceed. This will have the effect of capping the ends of the multiline with a 90 degree line. As you can see from the dialogue box, you can change this angle if you wish to give a chamfered end.
Next, click the "On" check box in the "Fill" section and then click on the Colour… button and select the fill colour from the palette. The Multiline Properties dialogue box should now look like the one in the illustration on the left. Finally, click the "OK" button in the Multiline Properties dialogue box and again in the Multiline Style dialogue box.
You are now ready to draw with your new multiline. Start the Multiline command, pick a number of points and admire your handiwork.
If you have followed this tutorial closely, your new multiline should look something like the one in the illustration on the right. Notice the effect of the various changes you have made compared with the Standard multiline style. About the Author: Andreea G.
