How to draw a three-dimensional view of a table using CAD

Here, take the cad14 version to draw a square table with a height of 800mm and a width of 1200mm (the thickness of the tabletop is 40mm, and the cross-section of the four legs is a square of 60X60).

First, change the workspace view to a three-dimensional view state such as the southeast isometric view, select Concept Display for visual style, and use the box command to draw a desktop with a length and width of 1200mm and a height of 40mm.

Then, use the box command, starting from the front left vertex of the desktop (close to the coordinate origin), and draw a foot with a length and width of 60mm and a height of -800mm (draw downwards)

Third, use the ar command, press Enter, select the table leg you just drew, set the array type to the default polar axis, and press Enter. The center of the array is the center of the desktop. To be specific, you can hold down shift+right mouse button and select "Two Points" "midpoint between", just click on the two diagonal points on the desktop. At this time, the following array modification table screen will pop up

Change the number of items from the default 6 to 4, and press Enter That's it

In order to strengthen the stability of the table, add four horizontal bars under the tabletop to fix it

Click the coordinate axis icon with the mouse, and place the mouse at the origin of the coordinates to pause Click, select Move Origin Only in the pop-up menu, and move the coordinate origin to the front left corner of the desktop

The rec command uses the coordinate origin as the starting point and the diagonal point of the origin as the end point to draw a A square of the size of the desktop, and then use the o offset command to offset the square inward by 60, resulting in the following square ring

Hide the three-dimensional desktop and table legs (specifically, select the desktop and legs The three-dimensional entity, right-click/Isolate Object/Hide Object), you will get the following picture (only keep the square ring)

Ull command (or enter presspull), put the mouse in any narrow area between the two white lines of the ring , click the left mouse button when the ring becomes a dotted line, then enter -60 (a negative sign means stretching downward), press Enter, and get four horizontal bar entities

Select the horizontal bar entity, and a To move the control, click with the mouse to select the vertical movement axis, pull it downward a certain distance, enter 200, and press Enter

Enter the unh command (or unhide) and press Enter to get the entire entity map

Then, use the Change the style to "Wireframe" and change the model view to "Parallel" (this can be achieved by clicking on the view control and visual style control in the upper left corner of the workspace)

Click on the visual style control/visual style manager ( Or enter the vis command directly), in the visual style manager that appears, click "Wireframe" (the second to last one), and then change the color and line type under the blocked edge to magenta and dot respectively, to get the following picture

The above is the wireframe diagram of a three-dimensional square table. If you want to change the three-dimensional diagram into a flat one, you can use the fl command (full name flatten), or the flat photography command fsh command (full name flatshot). .

What the fl command gets is the white wireframe plane in the southeast isometric view

And fsh can also set the dark line color to red and the line type to dotted line (the proportions are uniform) is 1, and the rotation angle is 45 degrees) to get

The wireframe drawings of three-dimensional or flat tables of other shapes are also produced in the same way.
