In CAD design, points are the basic elements that make up a drawing and the cornerstone of accurate drawing. In this article, we will take an easy-to-use CAD editor as an example to introduce several simple and easy-to-use CAD drawing methods to help you quickly improve your design efficiency.
1. Use coordinates to input and draw points
In CAD, you can use the coordinate input method to create points. First, determine the coordinate values of the point, and then enter the coordinate values of the x, y, and z axes. For example, to create a point at coordinates (1,2,3), enter the command "point" followed by the coordinate value. Note that by default, CAD takes the lower left corner of the current drawing as the origin, the positive x-axis to the right, and the positive y-axis upward. If you need to change the default settings, use the UCS command to redefine the coordinate system.
2. Use object snaps to draw points
Object snaps are a very useful feature in CAD that can help you create points on existing objects. To use object snaps, first select an existing object, then use the Point command and turn on the object snap options. Select the appropriate snapping method according to your needs, such as endpoint, midpoint, circle center, etc., and click the left mouse button to create a point on the selected object.
3. Use relative coordinates to draw points
Relative coordinates are a method of defining the position of a new point based on the relative position between the current point and the target point. To draw a point using relative coordinates, first determine a datum point, and then enter a coordinate value relative to that point. For example, to create a point with a distance of 30 units to the right of the current point, enter "@30,0". Similarly, you can create a new point by specifying the upper, lower, left, and right distances relative to the current point.
4. Use snap self-painting points
Snapping is another useful feature in CAD that can help you create a midpoint or intersection between two objects. To use snap self-draw points, first select two existing objects, then use the Point command and turn on the snap to self option. Select the appropriate option as needed, such as a midpoint or intersection point, and click the left mouse button to create a point between the two selected objects.
In conclusion, mastering the CAD drawing technique is essential to improve the efficiency of the design. By using methods such as coordinate entry, object snapping, relative coordinates, and snapping self, you can easily create precise points in CAD to better accomplish a variety of design tasks. In practice, choosing the right method to create points according to the specific situation will help improve your design level and work efficiency.
