Problem Description

Snap allows you to snap elements when hover over the mouse pointer close to data points.  By default, application uses the Keypoint snap mode. If you need another snap then you just single click on that snap (which is a temporary setting) and snap using that, but after that it again changed to default mode "keypoint". So at a time you can use only one snap mode. This document will explain how to use multi snap for different snap mode

Steps to resolve

One can select Multi Snap from Snap Toolbar. If the snap functions are not yet displayed as an extra toolbar, please select and activate these via CTRL + T from the dialog.

Then double-click on the button on the extreme right. Now this would have to be deposited slightly black, which indicates this is permanently active.
If other snaps  are clicked, they will only apply to one action.

You can also call up the settings for multiple snap via the search in the upper right corner.

It will open up with dialog box in which you can come to know that that there are actually 3 different Multi Snaps available where you can specify which snaps are used in each.

Here you can assign the multiple snaps in each snap (Multi Snap 1 to 3) and then activate desired catches.
