CAXA2011 machine version, the big flange bolt hole evenly distributed, how to give the centerline?
1) implementation of array command immediately pop-up menu, the menu and operation instructions immediately according to the current requirements, can make a circular array, the array array graphics results for the uniform distribution, a number of 4.2) pick up the elements with the mouse, pick the graphics into bright red display, pick up, with the right mouse button to confirm. As an operation prompt, the result of an array copy is displayed when the center point and the base point of the array pattern are picked up with the left mouse button. The meaning of [central] and [reference] points can be seen by tagging.3) the system automatically rotates the graph in the array according to [2: rotation] in the immediate menu.4) the system automatically calculates the positions of each insertion point according to the [3: evenly distributed] and  numbers in the immediate menu, and the angles between the points are equal. The array patterns are evenly arranged on the same circumference. The share value should include the entity picked by the user.5) with the mouse click on the immediate menu [3: evenly distributed], the immediate menu is converted to the content shown in figure 4-47.The meaning of the immediate menu is that a circular array is arranged in a given angle, the angle between the adjacent figures is 30 degrees, and the filling angle of the array is 360 degrees. The array filling angle meaning to the entity from the pickup location, around the center of the inverse angle clockwise turn, adjacent angle and filling angle can be determined by the array of keyboard input.
Draw the main body first, then confirm the center line of the bolt, draw the inner hole, draw the height, and distribute the cloth evenly
1, with the array evenly distributed, evenly distributed, even the central line together to choose, you can give2, the ratio is set in the plot
