How CorelDRAW curve shapes equal scaling

Q: How does the CorelDRAW curve shape equal scaling?

A: A friend asked how to draw a pair of railway tracks (including curves). If you draw a line first, and then copy one to the edge, you will find that the two curves cannot be parallel at the turn. Using the zoom function of the CorelDRAW itself does not exactly do this.

If you draw a square and ask you to zoom in or out: just hold down SHIFT and zoom in and out, but you can draw a rectangle, and you will not be able to pull it up or zoom out, not to mention the irregular graphics.

We use the "Convert Contour to Object function" to solve this problem:

First draw irregular graphics, calculate the proportion you want to shrink, for example, to reduce the 5mm, to select this irregular graphics, adjust the contour line thickness of 10mm, and then in the arrangement of the menu to convert the box into objects, after the break, you will get three of the proportion of lines, the need to choose which one.

This is practical, equivalent to the path offset in the illustrator, but there is no illustrator convenient and fast.

For example, the double parallel curves in the above picture are drawn using this technique.
