In the daily drawing process, we will always have questions about the application of certain functional commands, and then we will select the functions mentioned by the small partner to explain one by one, you may wish to collect and learn.
mirror image
Mirror [MI] I believe that everyone is already very familiar with it, I don't know if the novice partner has noticed that when mirroring text, there will be a reverse situation occasionally.
In fact, forward or reverse can be controlled by the value of the system variable, [MIRRTEXT], set its value is 1 or 0 can be customized to adjust the forward and reverse.
The following figure shows the effect under different settings.
Why isn't the attribute text mirrored in my normal text or tile reversed, but the normal text inside the tile is reversed?
This is a normal phenomenon, because in CAD, independent single-line text, multi-line text, and annotation text will maintain the readability of the text when mirroring, but if these words are in the block, they will be treated as graphics when mirroring again, so there will be a reversal.
If you do not want to reverse, you can blow up the tiles and then perform the mirror command.
Polar axis
Regarding the polar axis, many novice friends do not know how to use it, and will probably know that a certain length can be captured along the polar axis in the daily drawing, but in fact, the polar axis can help us quickly determine some special angles more often.
For example, when we draw the angle of some special drawings, we can set these incremental angles according to the needs of the polar axis function of the CAD, when our cursor moves to meet the angle, a green dotted line will appear in the CAD, which is the polar axis, the cursor is locked to the polar axis, at this time we can directly enter the distance value.
How do I set the increment angle of the polar axis?
Click the [Tools] menu - [Sketch Settings] - [Polar Tracking] tab in the CAD to set the increment angle.
Or right-click on the polar tracking button in the bottom state to pop up the sketch settings dialog and automatically switch to the polar tracking tab.
In the sketch settings window, a series of commonly used delta angle selections are also available, which can be selected directly in the drop-down list, or if there is a special angle, you can also add the increment angle yourself.
In addition to using the polar axis to determine the angle, it was also mentioned that the length can be determined by using the polar snap.
Since polar snapping only works when grid snapping [F9] is turned on, its settings are placed in snap and grid settings.
After setting up the polar snap, we can snap to the multiple length of the polar axis unit spacing along the polar axis.
In CAD, the polar axis, as a tool for determining the angle, can be used independently, and can also be used with object snapping in CAD.
