How to do 3dmax semi circular ceiling urgently, I hope you will teach me in detail

The specific operation steps are more complicated, so I won't talk about it, and here is the answer to the idea of building this model.

1, if this is a 360-degree semicircular top, we can use the rotation command (the Chinese version may be called turning) to make the basic part.

It is to draw the half arc of this semi-dome first, (if you don't have a good grasp of the size in 3D, you can draw it in CAD and then import it into 3D).

Then execute the Spline command, select the spline level, execute the profile command, and give the thickness parameters.

2. Select the inner arc of the contour and copy it (keep the line for the line, spare).

3. Perform the turning command to form the foundation of the semi-dome.

4. The vertical line part, the inner arc that was copied just now, is now used (the meaning of copying the inner arc is to make your line arc and.

Top Consistent), select the copied inner arc, execute the profile command, and give the line thickness parameter. Then extrude the width. (Because of the figure.)

You can repeat this to gradually reduce the extrusion parameters to achieve a multi-layer effect. ）

5. Now that you have made a vertical line, group the prepared vertical line, and execute the array command. (Note the pick arc.)

The center is, the center point. ）

6, the next is the horizontal line part, this is drawn in 3D, it is not easy to grasp the accuracy, you can in CAD, the inner arc according to your needs.

To divide equally, the width arc length of the line is cut, the thickness is offset, and then imported into 3D, turned, or chamfered sections.

I'll send you the flowchart below.

It's simple. I just can't describe it.,Approximate process.,max-create balls.,Convert poly and delete half.,Delete a little bit above.。 - Then select the face - chamfer command, pour a few times. This is quite cumbersome to say, but it is simply modeling work.

If the simple way is, max - create a ball, turn it to poly and delete half of it, delete a little bit on it, and then make a sticker and paste it up, and it's OK.

Cut off the hemispheres, then turn poly on each face, insert a little and then extrude in the direction of the negative number.

Build a ball, cut it in half, reverse it, and draw a sticker.
