Lamp Bracket – Part 2

Creating the Viewports       

Open your Lamp Bracket drawing.

Change to your Layout View and delete the Viewport – your Titleblock should be present.

Type in “MVIEW” to make your viewports

  • Type “4” for 4 viewports
  • Make a box to fit just inside your titleblock drawing area.
  • You should now have 4 views looking at your lamp bracket model.
 PAPER Toggle

PAPER Toggle

Double click on the Paper toggle to change from Paper Space to Model Space (or type in ms) 

Click in the top viewport.

Select the Top View Iconto create the top view of your model – note we still have a ways to go.

Do likewise with the Front and Right Side views – Leave the Isometric view as is.

Scaling the Views

Switch back to Paper Space – click the toggle or type in “ps”.

Select all the Viewports and change the scale to 1:2.

  • The Isometric viewport does not need to be to any particular scale.
  • You can use a crosses box to highlight all viewports and change them all at once.

Creating Profiles – Visible and Hidden Lines

The next step is to create 2D profiles from the 3D object for our visible and hidden lines.

Change all your viewports to 2D Wireframe. 

Notice that although the views look good they do not have hidden lines and also have extra lines for a proper Orthographic drawing.

What we will do is extract 2D Views from our 3D model using a command called “Solprof” – for Solid Profile.

Switch to model space (ms) and select the Top Viewport to make it active.

Type in the following:

  • Command:  Solprof and hit enter         (This command only works on solid models.)
  • Select objects:  Select the model (Lamp Bracket) in the top view        (The model will be selected in all viewports)
  • Select objects:  Right click or hit enter to complete your selection.
  • Display hidden profile lines on separate layer? [Yes/No] <Y>:           (Right click or hit enter to answer yes)
  • Project profile lines onto a plane? [Yes/No] <Y>:       (Right click or hit enter to answer yes)
  • Delete tangential edges? [Yes/No] <Y>:                       (Right click or hit enter to answer yes)

You have just created a 2D Top View profile of your 3D model.  

You have also created 2 new layers.  On the Home tab under the Layers panel open your Layers Properties dialogue box .

Notice the 2 new layer PH-42F and PV-42F.

  • The PH is the layer that holds the hidden line information of the extracted view.
  • The PV is the layer that holds the visible line information of the extracted view.
  • The 42F is a random assigned name and therefore may be different on your computer.

Before extracting the profiles of the other views we need to rename the new layers to a logical name.  

Notice also that the hidden layer was assigned the Hidden Linetype.  This will only happen if you have the Hidden Linetype loaded before doing the Solprof command.

This would probably be a good place to save if you haven’t done so.

If you temporarily move your model in the top viewport you will be able to see the extracted 2D view.

Now go to the Front, Right Side and Isometric Views and repeat the extraction process.  Be sure to rename after each extraction otherwise you will have a hard time determining which view is on which layer.

When finished extracting views you should change the colour of the Hidden and Visible layers to the desired colours.

To see the 2D extraction drawings turn off or freeze the layer you created your model on.

Change your linetype scale (ltscale) to the appropriate amount to view the hidden lines properly (try 10).

We now have the necessary 2D drawings but there is still a lot of work to be done to create the final Orthographic drawing.

Adding Center & Dimension Lines

Create new layers for each viewport for the Center and Dimension lines.  Plus give them the appropriate colours and linetypes.

Change to the Top – Center layer.

Make sure you are in Model Space (ms).

Select the Top Viewport and add the center lines.

Change to the Top – Dim layer and add the dimensions.

Notice that the centerlines and dimensions show up in the other viewports.  The next section will solve this.

Freezing Layers in Current Viewport

While in model space and in the Front Viewport select Freeze in the Current Viewport the Top-Center and Top – Dim Layers.  This only freezes these layers in this current viewport.

Do the same while in the Right Side and Isometric viewports.

Go to the other viewports and switch to the appropriate layers then add the center & dimensions as needed.

Freeze in the Current Viewport for the appropriate layers in each of the viewports.

If needed, rescale your drawing to an appropriate scale (1:2) – remember to change to Paper Space (ps) and select all the viewports. 

Finishing the Drawing

Lastly, we need to lineup the views and turn of the viewport outlines

To line up the views to each other while in paper space, draw lines from the edges of the views to the viewport edge as shown below by red lines.

Then while in paper space move the viewports from the end of one of the lines draw to the end of the other views line as shown below.  Then delete the lines used to line up the views (the red lines shown).

The last step is to create a Viewport layer and select the viewports and put them on this new layer and then freeze or turn off this layer.

Congratulations you did it.  After a bit of practice this process becomes fairly quick to do.
