How to draw this 3d drawing as a 3d solid in the autocad ?

[hemal]

Kindly help to draw this figure as a 3d solid. Any hint or suggestion will be highly appreciated.

One option would be to create a 3D cube then slice away portions of the cube or subtract from it.

• Draw a cube,
• Draw lines on the edges so that snaps work at the right points,
• Cut all corners with the _slice command, specifying a section plane at three points,
• Where the cut planes cut off unnecessary parts, you need to set the _both option to save the cuted pieces,
• Glue the cut pieces back where the extra cuts are (_union command),
• Rotate USC with the Z axis along the groove that is drawn on the top face,
• Draw a box along the groove with a margin in length,
• Subtract this box from the main solid (_subtruct).

That is, the idea is that everything that can be cut off is cut off by the Slice command. And we make all the recesses by subtracting other solids.

Note that the sides of the groove are not exactly parallel. One side has a slope of 2/3 while the other is 0.673... (35/52)

Rather than using a box to subtract create a closed polygon using the noted dimensions, extrude then subtract.

Tooting. In such cases, it is convenient to create a cube and then modify it by simply dragging the vertices to the desired points.

BTW AutoCAD (and all its clones) has very convenient modeling - you can simply drag and drop "subobjects" (surfaces, edges and vertices). Subobjects can be selected simply by holding CTRL. This method (together with the selection of sub-objects by the selection frame) makes it easy to stretch or shrink large assemblies of dozens of solids with a single _Move command.

And if you optimize the number of clicks, it may be more profitable to draw a closed polyline on the top surface of the box along the groove contour. Then the _presspull command will help you make a groove right away, without even having to subtract the solids. To some extent, the smart _Presspull command compensates for the absence of the Drill command in AutoCAD.

Use 3D poly lines (3Dpoly command) and subtract according, easy.
