mouseMouse as a pointing device has become indispensable in design applications. Each applications may have unique function on mouse buttons. We will discuss about it here.

View control also have important role. You will do a lot of zooming out, zooming in, panning, and other control during the design. Let’s make you comfortable with it before we continue further.


Mouse Button Function

mouse button

  1. Left button (1) is called data point (DP) in MicroStation. When we place an object, we will need to define a data point. Either a start point, center point, next point… any kind of points! We can define it by clicking the left mouse. I guess that’s why they call it data point. We can also use data point to activate tools from task navigation and as OK/accept button.
  2. Right button (2) is called as Reset. Since MicroStation V8 XM, we can choose not to use it as reset button. But let’s just use it as reset button first. Reset is used to cancel a running process or finish using a tool.
  3. Tentative button is when you press both left (1) and right (2) button at the same time. We use this for temporary snap.
  4. X Button is your mouse mid button. It’s only available for 3 button mouse. But I guess no body using CAD still using 2 button mouse anyway 🙂
    • Clicking this button will activate/deactivate pan (no need to hold it).
    • Clicking it twice will activate fit view. MicroStation rescale your view to show every objects in your drawing.
    • Scrolling this button will zoom in/zoom out the drawing area.

When the first time you use Reset button, you may see this dialog. MicroStation will ask you whether you want to use right click for Reset or pop up menus. I suggest you to leave the default value: use it as reset button.

first reset confirmation

That’s the basic. We can combine the mouse button with [ctrl], [shift], and/or [alt]. You can see all this mouse function from MicroStation menu Worskpace>Button Assignment… Don’t try to change anything yet. Just take a look for what you can do with them.

View Control

view control

You can find view control toolbar under each view. If you are familiar with Windows applications, it shouldn’t be hard. We will discuss most used tools first, and the others later. Not all of them available for 2D drawings, so you might not see some of them.

zoom in-zoom out

The magnifier button with the + is zoom in. Clicking it will enlarge your drawing, just like you move your eyes closer to your paper to get a better look.

window area

We can use window area to magnify selected area in our drawing. You need to define two data points when you use this tool.

Fit View

Fit view will adjust the drawing view scale automatically until you can see all of your object. Alternatively, you can double click your X-button.

Pan View

Pan view is used to pan or move your drawing area. Just like you move your paper around to see another part of your drawing. Activate it, and click your data point to pan view. Alternatively, you can press your X-button.

View Previous - View Next

These are just like back and forth button. Just like undo and redo. But only for view control tools.

Hint: If you use AutoCAD, undo and redo will also affect the view control. But not in MicroStation.

We wil
l discuss more about view control later.
