SolidWorks software is a 3D mechanical design software and the world's first 3D CAD system based on Windows. It uses Windows OLE technology, intuitive design technology, advanced parasolid kernel and good integration technology with third-party software. It has three characteristics: powerful, easy to learn and use, and technological innovation. One of the software used. Next, the editor will use the SolidWorks version to make a rose, and intersperse various skills in the production process to help everyone better understand and learn SolidWorks.
Below is the picture of the finished product, isn’t it very beautiful, come and learn with me!
1. Open the software
and open the interface of SolidWorks2019 as shown in the figure above. Don’t be confused by so many things. The basic tools we use are all in parts and assemblies. If you want to build a large project, I suggest you use the part diagram first. Draw each small part bit by bit, and then use the assembly function to assemble each part; for the engineering drawing that is not too large, it is enough to use the part drawing. This article draws roses under the part drawing, and The engineering drawing function is to draw in the 2D environment.
2. Enter the drawing
Click the part button to enter the drawing.
After entering this interface, the first thing to do is to select a datum. Choosing a good datum will help improve the efficiency of modeling. Here, the editor takes the previous datum as the datum. Right-click the front view datum plane, click the "Sketch" button in the dialog box that appears, and you will enter the sketch drawing interface based on the front view datum plane.
3. To draw stamens,
first use the straight line command on the sketch interface to make a vertical straight line at the origin, and set the length to 3mm, and then use the spline command to draw a curve.
Note: The places where the spline curve and the straight line touch are set to be horizontal to prevent errors in future drawing.
Next, use the rotate surface command on the feature interface, and the rotation axis is the vertical line we drew, so that our stamen is drawn.
4. Establish a reference axis
Select the reference axis command in the reference geometry in the feature interface to establish a reference axis, which will be assisted in many subsequent steps. Here, the editor will use the front view reference plane and the right view reference plane The line of intersection is the reference axis.
5. Draw the petals
This step requires us to draw three layers of petals. The three layers of petals sound complicated and time-consuming, but in fact, we only need to draw one for each layer, and then use the array to draw three layers. First use the spline command to draw a curve as shown in the figure below (the origin coincides with the end point of the curve, and the horizontal distance from the upper end point of the curve to the reference axis is 15mm, and the vertical distance to the lower end is 27mm) and then click the rotating surface in the surface
interface command, the rotation axis is the reference axis we established, and the angle is 100 degrees.
Note: If the rotation axis cannot be selected in the surface view, you can click the reference axis first, and then click the Rotate Surface command, and the system will automatically select it for us.
Next, we create 2 more datum axes in the same steps.
The number of arrays in this picture is three, so the angle should be less than 120 degrees, and the direction of the second petal is reversed, and the direction of the third petal is symmetrical on both sides. At this point, it should be noted that for the sake of beautiful drawing, the height and length of each sketch interface are different, and the angle of each surface interface also changes, which depends on your own preferences.
6. Make the base
Next, I want to make a base for the rose. In the same way, in the surface view, use the reference axis as the rotation axis and the height is 2mm to rotate the surface.
7. Separate the petals and the base
In order to prevent errors in the array, you need to use the trim surface command in the surface interface to cut the surface and separate the petals and the base.
8. Thicken petals
Use the thicken command on the surface interface to thicken each petal with a thickness of 0.2mm.
Note: Thickening is to thicken inwards, and the combined result must be turned off, and the same steps are performed four times.
9. Set the chamfer
Set the chamfer to make the petal look more natural. Use the chamfer command in the surface interface to set the chamfer, select the edge of the petal, and set the angle to 6mm, 4mm and 3mm respectively.
10. Array petals
In the feature interface, click the circular array in the linear array, and the parameters are as shown in the figure.
11. Make the flower stem
Click the front reference plane, draw a sketch, use the spline command to draw a curve downward at the origin, and set the height of the curve to 70mm.
Note: The two ends of the curve should be vertical. This is to prevent the slope from appearing when scanning the curve.
Next, click the scan command on the feature interface, select the curve, click the circular contour, and the diameter is 3mm.
12. Drawing the leaves
Click the front reference plane, draw a sketch, and use the spline command to draw two curves.
Switch to the surface interface, click Extrude Surface, and stretch the two curves on both sides.
Click on the top view datum plane, draw a sketch, and switch the view to visible hidden lines to facilitate the next drawing.
Use the spline curve command to draw two curves, the style can be freely selected, as long as the spline curve is in the two boxes of the upper view.
Exit the sketch drawing, and click the Trim Surface command in the surface interface, as shown in the figure. 
Use the method above for thickening the petals to thicken the leaves.
13. Draw the torus
Front view plane, sketching, draw a line with the spline command, then put a point at the end point, and remember this point!
In the surface interface, use the datum plane in the reference geometry, draw a datum plane based on a point on the curve we drew and the curve, and then draw a curve based on this datum plane, and repeat 3 times on the straight line. (Except for the point in the previous step) 
In the surface interface, click on the lofting curve, select the three curves and the point we made at the beginning in turn, and the guide line is the curve connecting them.
14. Thickened surface
Switch to the feature interface, click the circular array in the array command, the rotation axis is the reference axis, and the number of arrays is ten.
In this way, the overall outline of the rose is finished! If you follow the editor to do this step by step, you will definitely feel a sense of accomplishment in your heart!
Let's take a look at our results! 15. There is no soul in drawing roses without color, but due to the length of the article, the coloring part is relatively simple, so I won’t write them down here one by one. The picture below is the color I added, isn’t it
?
Is it beautiful?
