Many beginners in CAD drawing, when using the Haochen CAD software to create drawings, do not know how to display the projection images of parts Or rather, is it by using the two views of a part to draw the third view? It’s actually very simple; it can be achieved by using the hole-axis projection and angle projection functions in the HaoChen CAD software. Next, I’ll share with you some tips on using the hole-axis projection and corner projection functions as a beginner in CAD drawing! CAD drawing: To perform hole-axis projection in HaoChen CAD mechanical software, select 【HaoChen Mechanical (M)】→【View Tools (V)】→【Hole-Axis Projection (H)】, and the “Hole-Axis Projection” dialog box as shown in the figure below will appear. 1. Creation method: Manual creation method]: Set manual projection. [Auto Creation Method]: Set automatic projection. 2. Projection mode: Normal projection mode] – Set the projection direction to horizontal. [Any projection method]: Set the projection direction at a specified angle to the axis. 3. Projection direction: Specify the angle value for the projection direction. 4. Measurement: Determine the angle value of the projection direction through measurement. 5. Do not draw center line: Do not draw a center line. [Bidirectional]: Draws center lines in both horizontal and vertical directions. [Horizontal]: Draw a horizontal center line. Vertical]: Draw a vertical center line. Select the “Manual” mode, enter the other data—then choose the center line as the axis target—followed by selecting the contour point positions of the shaft or hole—press Enter to finalize the selection—and specify the projection location to complete the manual creation of the projection. As shown in the figure below: For CAD drawing – corner projection, in the HaoChen Machinery CAD software, select 【HaoChen Machinery (M)】→【View Tools (V)】→【Corner Projection (A)】, and the “Corner Projection” dialog box will appear, as shown in the figure below. Select the \"Projection\" direction as \"From front view to top view\". Then select the highest point in the top view and the far left point in the left view. Specify the leftmost point and the rightmost point of the front view again. Finally, select the leftmost and rightmost points of the left view. Just press Enter to complete it, as shown in the figure below. The above are the steps for displaying the projection of a part in the HaoChen CAD software.
