![]() ![]() You will see separate selection handles around each letter. The result is a grouped set of polylines in the shape of the original type. To allow conversion to a 3-D object, you also need to select a typeface in the TrueType format.Īs the first step in creating a 3-D object, convert the type block to polylines (much like the ones you drew earlier with the Polyline tool) by using the Tool->TrueType to Polyline command.For best results, avoid typefaces and styles with complicated outlines, since this would also drive up the file size and the processing time: sans-serif typefaces such as Helvetica or Avant-Garde are a good choice. Now choose a typeface, size and style from the top three commands in the 'Text' menu.When done typing, choose the Arrow tool, leaving the new text block selected.Type a few letters, such as your initials (to keep file size and processing time down, we cannot have a large amount of text).The result is a symmetrical 3-D shape based on the 2-D profile you drew.Ĭhoose the Text tool (the 3rd from the top in the left half of the toolbox).Ĭlick in the document window to indicate the location of the type. With the pointer (the Arrow tool), drag a selection box enclosing the locus and the profile, leaving both items selected.Ĭhoose the Model->Sweep command ( sweeping is another name used for the lathe operation). This picture shows where to click for the sample profile shown previously. This is used to indicate the axis of rotation (the imaginary line around which the profile swings as it creates the 3D object). An example of a completed profile is shown in this picture.Ĭhoose the 2D Locus tool (to display its icon, click and hold on the 6th tool from the top in the right half of the toolbox).Ĭlick to place a locus symbol (a white 'X' in a black box) on a corner of the profile. To complete the profile, return to a location aligned below the starting point, and double-click.To constrain the line segments to vertical, horizontal, and 45°, hold down the Shift key while clicking. Click to establish additional vertices representing one half of a front view of the pedestal.Click near the middle of the grid to establish the starting point of the profile.Choose the Polyline tool (the 5th from the top in the left half of the 2D Tools palette).ĭraw the profile for the pedestal, using the Polyline tool in a connect-the-dots fashion to create a series of connected straight segments.Make sure the 2D Tools palette is visible (otherwise, display it using Windows->Tool->2D Tools). ![]() The document window will update to show a front view of the model space. Switch to front view, using the View->Standard Views->Front. Make sure to save often as you continue to work. Save the new document: File->Save As, enter any filename you want (this document will not be posted on the web site directly).A new untitled document window appears.Our final product will be a simple scene containing a logo made up of a few text characters (e.g., your initials).įind the MiniCAD application icon and start the program A roof obtained by repositioning and rotating a pyramid.Walls carved using a solid subtraction operation on cubes.A simple building assembled from imported 3D primitives:.Later we will work directly with basic 3D shapes called primitives, combining them using solid operations.Īfter some initial setup, we can proceed to create the elements in our scene: In this first phase of our 3D project, we will use the most common modeling tools: we will start from flat 2D shapes, converting them to 3D using two techniques generally available in all 3D programs: extruding and lathing. It does, however, follow the basic user interface approach used by all the dominant players, and it embodies all the major aspects of 3D work: modeling, rendering, and animation. Since the 3D marketplace is very fragmented, MiniCAD is not the only 3D programs you will encounter. It can also be used, however, to create virtual 3D scenes-such as the ones we will incorporate in our web pages. This type of software is primarily used for dimensional design (i.e., to create blueprints of real objects). MiniCAD is widely used on the Macintosh for Computer Aided Design (CAD) applications. This section of the directions may not apply if you work on the project elsewhere. Information that pertains specifically to the way the ACG Lab operates.
