Can we draw something like a flower in technical softwares?
Yes you can do it. There are some advanced features avilable in some technical softwares which can be used to model complex surfaces such as a petal of a flower. I have used SolidWorks 2010 to model a flower, I guess the steps below will be helpful.
Please don't hesitate to contact me if you don't understand these steps.
First of all, load SW software version avilable in your PC, and select the sketch plane and creat a point to begin the drawing. Once it's over draw a 3D sketch which ends at it's staring point as shown.
And then, select a cross plane to draw a path shetch using the Spline tool which connects the widest distance on the 3D sketch.
Then use Surface-Fill feature and select the 3D sketch as the path boundry, and the Spline as the Constraint curve.
Once it's build, thichen the surface, which will help to build a pattern.
Then draw a simple circular extrude in the center, of the drawing in the first plane you selected for your drawing.
Now using the circular pattern feature, create the number of patterns it means the number of petals you need.
And Finally, draw the necessary needing such as the stem, and the other things to complete the flower. And here comes your Flower.
