MicroStation V8 in 3D - The Drawings Are So EasyMicroStation has always been a 3D design application, but it is more commonly used as a 2D "electronic drawing board" – what a waste! Printing from a Sheet ViewThis sheet model has only one drawing sheet referenced to it, but we could have moved this sheet aside and attached more borders and views. However, we will only have one drawing sheet per model for this exercise, as it can make finding the sheets easier in the future. To print this out, it is simply a matter of first defining the print area (note the active points for manually snapping a fence block). We can then set the printing attributes and send it to a Letter or A4 printer, which we will assume is attached to our machine as the default Windows printer. Since the border is actual "Paper" size, we can set the scale to 1 : 1 (it will be slightly less than this when the active points are used to place the area defining fence). This sheet is mainly pictorial, so the fact that we set the scale to 1 : 18 when we referenced the Assembly model earlier is of little importance.
Sheet Models With Dimensioning and TextThe next sheet model we will create is to have top views of two components of the frame, referenced at full size. We will position them on the sheet, then add dimensioning and text. Create a Drawing Sheet for the Horizontal Socket Components
Now we have two components referenced, we can adjust their positions (Using the Move Reference tool) within the border as necessary to compose a drawing sheet. Placing Dimensioning and TextWe will not go into any great detail about dimensioning and text placement, as the techniques are exactly the same as for 2D drawings. The attached dimension styles are metric, but this may easily be changed under Element > Dimensions if you wish. You may also import dimension styles of your own.
3. Place dimension elements as required. Note that we can place the associated dimensions as if we were working in a simple 2D design, no need to concern ourselves about depth, as we would if we were dimensioning in a conventional 3D model. 4. Select the Place Text tool, choose the General 1:1 text style.
5. Make the Annotations level active. 6. Place text annotations as required.
Component detailsThis sheet will show the ends of the long horizontal and roof frame tubes. The saved views were created to only display the required detail, with the saved view of the roof frame rotated to make it appear horizontal.
More Complex Referencing and DimensioningThe next sheet will show a typical roof corner socket. In the model, this is rotated both vertically and horizontally with respect to the design X and Y axes. However, the saved view we will reference has been rotated to make the component representation easier to follow. We will also add some of our own geometry in the sheet model.
The next sheet will present scaled sub-assemblies, with the hidden geometry
removed. 1. Create a fifth sheet model in the usual manner; this model will be named Sheet
5, with the description Top Upright Assembly. 2. Reference the appropriate Portrait border DGN, either A4 Portrait
border.dgn or Letter Portrait border.dgn. 3. Reference Tent Frame.dgn (the active DGN), selecting the Model
model and the TP Top saved view. Set the scale to 1 : 5. 4. Reference the Tp Iso and Tp Front saved views from the same
model, also at a scale of 1 : 5. 5. Position the sub-assemblies within the border as required. 6. Dimension the side view, place text and additional linework as required. Note: There is no need to do anything about the scale – the
dimensions are actually associated with the Design model, not the
geometry as it appears in the Sheet model. This is one of the most
powerful features of the "Sheet Model" facility. 7. Select the Set Reference Presentation tool from the References
tool box, set the Presentation to Hidden Line.
8. Identify each of the sub-assembly references, accepting each one
with a data point, update the view. The views will now appear with "Hidden Line" or "Visible
Edges" presentation. Now, sheet 3 would benefit from this presentation…
The next two sheets have the views of the lower upright assemblies. 1. Create a sixth sheet model in the usual manner, this model will be named Sheet
6, with the description Lower Rear Upright Assembly. 2. Reference the appropriate Portrait border and Tent Frame.dgn,
selecting the Model model and the BRP Top saved view. Set the
scale to 1 : 5. 3. Reference the BRP Iso and BRP Front saved views from the same
model, also at a scale of 1 : 5. 4. Position the sub-assemblies within the border as required. 5. Dimension the top and left views; place text and additional linework as
required. 6. Select the Set Reference Presentation tool from the References
tool box, set the Presentation to Hidden Line and convert each
of the sub-assembly references, as in the previous exercise.
7. Create sheet 7 as for sheet 6, except use the Lwr Top LHS, Lwr Frnt Top
RHS, Lwr Frnt Left Iso and Lwr Frnt Side saved views.
The next sheet model will combine full-size details with a scaled down
component. As mentioned earlier, this is no problem, the dimension elements
always see the actual model, not the scaled reference geometry. 1. Create an eighth sheet model, named Sheet 8, with the description Upright
Components. 2. Reference the appropriately sized Landscape border. 3. Reference the active DGN, selecting the Model model, the Mskt
and the Foot Top saved views. Set the scale to 1 : 1 for both. 4. Reference the Upright saved view from the same model, at a scale of 1
: 10. 5. Position the sub-assemblies within the border as required. 6. Dimension the views, place text as required. 7. Create sheet 9 as for sheet 8, except use the Roof Cassy saved view at
1 : 2 scale, Roof Core, Cap and Roof Skt saved views at 1
: 1. 8. Change the Presentation of the center assembly to Hidden Line.
That’s it, folks! Now you have nine drawing sheets ready for printing in the usual way. The starting point for this type of drawing composition is the creation of saved views for all of the components to be detailed. To save time, all of the saved views were created for you here, but this is a simple process, well within the capability of most MicroStation users. Much can be learned by opening the Model model and applying the saved views one at a time, noting the shape of the view, levels turned on etc. Once the model is created, the rest is pretty much 2D, as evidenced from the exercises in this article. Note: The publication of the tent frame design in this article is purely intended for an exercise in creating drawings. The design is copyright and any drawings thus created are not to be used to manufacture actual tent frames.
