【 Weak current College 】 AutoCAD application analysis and solutions to common problems

CAD is a modern product design and engineering design important secondary means that it is widely used in construction, mechanical, chemical and electronics and other fields. Not only can greatly reduce the CAD labor intensity, can also improve design efficiency and quality, but also in the design process often encounter some problems if not properly addressed, it will affect the design efficiency.

Application performance of AutoCAD FAQ, analysis and solution

1 performance: for Offset and Move operations, without offset or move after the segment or objects.

Analysis: as offset or move after the segment or objects outside the plot area, and therefore cannot be displayed, but the root cause is not setting the correct shape boundaries.

Workaround: in the Startup dialog box, select the use the wizard, choose any advanced settings or quick settings.

2 regional settings dialog box

In the angle and length of the blank, fill in the appropriate values to meet the needs of the drawing, not beyond the maps. Or, in the Startup dialog box, select the default settings, and then select the default settings of the metric system.

3 graphic distortion

Analysis: the computer displays a circle, is a very short straight line segment and became a close circle, with the naked eye usually not recognized. However, a small circle amplification, as will the approximate representation of the circle on the magnifying glass, naturally sees a polygon.
Workaround: click on the menu bar of the parent menu item "view" of second-level menu item in the first, second or third, they are "redraw" and "to build" and "all" computer-generated graphics.

4 performance: use level menu item "drawing" under the "text" command when you enter text, the text size is not changed, that is, the text height cannot be set in accordance with the users of the x-height. Both set font height is the number, the computer displays the text size is unchanged.

Analysis: in the text style, Word high has been set, and uses write text command to display the font height is fixed.
Workaround: open the main menu under the "format" of the "text style" dialog box, the "height" of a column is set to 0.

5 Chinese does not display

Analysis: writing text, the text style in the text style must be used, otherwise the text will not be displayed.

Workaround: in the "text style" dialog box, in addition to the standard style, and then create a text style, in standard style and new style, place the letter font style and font style.

6 text rotated 90 °

Analysis: this is clearly not the rotate command results, because the font set rotation, is the entire line of text entered for 90 ° rotation, instead of each word in their rotation. Produce the reason for this is that the "font-style" in the selected font is wrong. Usually the font name drop-down list box at the beginning and the end of the two fonts get confused, because the two font name resemblance, if same is fangsongti, then at the beginning of the font name only at the end of the font name by the "@" symbol.

7 actually displayed as solid lines

Analysis: style, the proportion of properly.

Workaround: at the command line, enter the command "ltscale" (linetypescale, linear scale), until you enter the scaling factor of the original proportion of the solid lines to dotted lines as appropriate.

8 performance: "pattern" command cannot be executed.

Analysis: this can be either of the following reasons. One reason is the implementation of the "pattern" command, to fill the region has not been filled in, or were filled in with white or black. That happens because a "pattern" in the dialog box to set the "proportional". To fill the region has not been filled in with the pattern, because the proportion is too large to fill pattern is infinite expansion, appears in the want to fill in a small region of local design is just a blank, or you can only see a few scattered in the pattern of local patterns. Conversely, if the scale is too small to fill pattern is infinite zoom out, looks like a color, if the background color is white, the display is black color, if the background color is black, the white color, which is previously mentioned were filled in with white or black.

Reason two: prompt "could not find a valid pattern fill boundaries".

Fill boundaries are not closed

Solution: for the first reason, in the "pattern" dialog "proportional" to adjust the appropriate scale factor. For the second reason, as long as the back look at graphics of the sealing.

9 toolbar placed in the user interface

Workaround: make the user interface, find the occluded "lost" in the toolbar. Sometimes, the toolbar also may be dragged to the desktop edge, or hidden behind the taskbar, you want to hide the taskbar, a careful look.

10 performance: used to store the file on disk is not corrupted, but the file cannot be opened.

Analysis: as the current AutoCAD update extremely fast, version number, when users are on different computers using different versions of the open previously saved files, very susceptible to the problem could not be opened. For example, high version of AutoCAD to open to low versions of AutoCAD format to save files, and the low version of AutoCAD may be unable to open higher version of AutoCAD Format saved file. Or, use a different version of the format open file, an error occurs.

Workaround: convert saved format. Method is to open the main menu "Tools" menu, select the last item "Item "dialog box.
