Hi folks.
SU allows that.
To move an object, for example grabing a cube by one vertice and snapping that vertice to the endpoint of a line, you would follow these steps:
1 - Select the object to move with a click if it is a group or component, with a window select or with a triple click if all its geometry is connected but it is not a group or component.
2 - Select the Move Tool.
3 - Hover the cursor over the selected object's vertex that you want to grab untill you get a snap indicated by a pop-up stating "Endpoint".
4 - Click to grab the object.
5 - Move the cursor on the endpoint of the line untill you get a snap indicated by a pop-up stating "Endpoint". The object shall follow the cursor after being grabbed.
6 - Click to place the object.
In all these steps, a click in a press THEN a release of the left mouse button (LMB). Do not press the LMB to grab the object and keep it down while draging the object.
I suggest that you watch the video tutorials on the Move Tool, the Rotate Tool and, of course, that you read the help about these tools to get an idea of all the subtle modifications that you can add to these tools with the press of some modifier keys or the use of the Measurement Window to input exact values that can be used to specify distances, absolute coordinates or relative coordinates, just to name a few.
By the way, watch the status bar on the lower left of the model window. It is always telling you what it expects from you.
And finally, all the tools related to positioning the view like Pan, Zoom and Orbit are active even in the middle of an operation like Move, Rotate, Copy, Scale, etc. You can even change scene, rendering mode, turns shadows on or off, etc during such operations.
Experiment and have fun.
Just ideas.
