1. PRIMITIVES REVIEW

Primitives consist of basic elements such as lines, circles, arcs, boxes, etc.
Primitive tools typically have dialogue boxes associated with them to control the method of primitive creation (ie. by edge, center, diameter, copy, etc.).
Remember to use these dialogue boxes to control the ways in which your tools are working.

2. TOOL BOX ORGANIZATION

Within the tool bar, additional sub tools can be accessed by holding down any tool with a triangle in the lower right hand corner.
These sub-tools can be pulled out and revealed as their own tool bar as well.

3. CURVES

Point or Stream Curve: [5 th tool in the Linear tools bar] This is a line based, simple curve that is very quick, but does not provide a lot of control or exact geometrical specification.

B-Spline Curves : [Tools Menu/ B-Spline Curves/ Create Curves]
Method: Control Pts, the curve is drawn by pts which effect the gravitational pull acting upon the curve.
Method: Through Pts, the curve is drawn by pts which are directly in the path of the curve….more direct.

Bezier Curves : [Tools Menu/ Composite Curve]
Mode: Bezier Curves, this curve is defined be tangential lines. Their length effects their impact on the curve.

NOTE: Don’t just trace the drawings. Work to figure out the geometric rationale behind the design. This will take you further towards a correct model and geometry (ie Helix tool for the Guggenheim)

4. LEVELS (aka LAYERS in other programs)

Conventionally, each level in Microstation is given an independent color. To begin, work this way in order to keep your drawings organized. It may be that you will adjust this system as your model develops.

5. ERASING LAYERS

[Settings Menu/ Level/ Manager] Highlight the layers you wish to delete. Press delete.

6. CHANGING THE COLOR SETTING OF A LEVEL

[Settings Menu/ Level/ Manager] Within the Level Manager, click on the box in the “Color” column next to the layer you wish to associate with a color. This will set the “by level” color of this level. When you return to the main screen, ensure that the level creates this color by checking the “By Level”option in the Color Pull down menu at the top of the screen.

7. MODIFY TOOLS

Modify element [ Modify/ 1 st tool] This very generic and useful tool can be used to alter a primitive multiple ways, including: a point (by clicking on a point), an edge (by clicking on a midpoint of a segment) or size of an element (by clicking on a point of a circle, box, etc.).

Delete part of an element [Modify / 2 nd tool]Breaks an element into two separate pieces.Deletes a part of an element.

Extend line [Modify / 3 rd tool] Extends a line, option to type in Distance of resulting length.

Extend two elements to intersection [Modify / 4 th tool] Extends two lines to each other

Extend element to intersection [Modify / 5 th tool] Extends one line to another, or to an implied intersection.

Trim element [Modify / 6 th tool] Cuts one object. Option: pre-select two elements with the control button to cut another.

Intellitrim [Modify / 7 th tool] More complicated than the regular trim element, which works in most cases. Combines defining area to trim into the tool.

Insert vertex [Modify / 8 th tool]

Delete Vertex [Modify / 9 th tool]

Circular Fillet [Modify / 10 th tool]

Construct Chamfer [Modify / 11 th tool]

8. GROUP TOOLS

Drop element [Groups/ 1 st tool] Makes separate pieces out of a single shape.

Create complex chain [Groups / 2 nd tool] Makes a single line out of independent pieces.
Method: Manual- you must click on each independent piece that will make up the shape.
Method: Automatic- allows you to click on one piece and a single shape will be automatically constructed (disconnected pieces are connected).

Create complex shape [Groups / 3 rd tool] Makes a single shape out of independent pieces. In order to extrude, you need to have single elements, typically made with this tool. See Methods above.

Create region [Groups / 4 th tool] Uses Boolean logic to make shapes out of the unions, differences, or intersections between two or more elements. There is also a flood option.

9. MANIPULATE FORMS

Move element [Manipulate Forms/ 1 st tool] Applies a vector to an element. Click on or outside element once it’s selected and move in desired direction, typing in distance in Accudraw if you like.

Copy element [Manipulate Forms/ 2 nd tool] Copy an element. Method: type in # of copies in dialog box if more than one copy is desired at the same distance from one another.

Scale [Manipulate Forms/ 6 th tool] Methods: Active (type in scale change), 2pt or 3pt

Rotate [Manipulate Forms/ 7 th tool] Methods: Active angle (type in angle), 2pt or 3pt

Mirror [Manipulate Forms/ 8 th tool]

10. ACCUDRAW

Accudraw is on when you see a dialog box where you can enter distances (XY&Z) of elements that you are drawing. Your curser will also have a box around it with a square crosshairs. This works with many tools (drawing lines, copying, scaling, etc.).

(If Accudraw is not on, click on the green and red crosshairs symbol in your toolbox Attribute toolbox at the top of the screen.)

To ensure that you are drawing at right angles, allow your line to lock into the appropriate direction. (When your line become thick). Press enter to lock into this direction. When drawing at an angle, Accudraw will adjust to this anglular field. To return to the xyz orientation, press Shift and “T”.

11. SELECTION / PRE-SELECTION

You can pre-select before using other tools to alter more than one element at a time.

a.Using arrow (aka element selection) tool, click and drag to make a rectangle around the things you want to select.
b. Use arrow tool to click on individual elements, holding ALT button to add to your selections.
c. Use power selector (arrow with light bulb). Offers different methods (areas), modes ( add/subtract from selected elements), or click on arrow at bottom of box to select by colors, element type, levels, etc.
