NOTE: If the Boundary command does not work check the following points: This creates a closed boundary for the building on the correct layer Draw > Boundary > Pick Points - pick a point in the middle of the building framework lines.The landscape drawing is constructed by referencing the known positions of points and lines of the building - as it would be constructed on-site These have been created using the Offset command. Notice that a layer called 'Framework' has been created and there are building framework lines already drawn. This drawing contains some layers for a creating surfaces and a kerb for a simple landscape scheme (shown completed below) Using the Line command produces fragmented and less managable drawings TIP: Always draw lines using the Polyline command. Export to CorelDraw or Mcolour for plan graphics, hatching areas in AutoCAD and listing of area quantities are good examples of extended functionality using these methods NOTE: The creation of closed boundary polygons and comprehensive layer system is useful for other outputs from AutoCAD and 3rd party applications. This tutorial explores some of the basic useful commands to create clean, simple, accurate lines in AutoCAD Together with a comprehensive layer system based on 'objects' and the use of closed boundaries using a framework layer, and the boundary command, the use of appropriate AutoCAD tools make transition into 3D much easier. Good clean drawing techniques are essential to produce good looking scenes and benefit the drawing as a whole. NOTE: Creating separate objects from one layer in MAX/VIZ is handled on the import options dialogs in MAX/VIZ This drawing contains an example layer system used for easy import to MAX/VIZ This is a straight forward process that allows you to think 'objects' right from the start The main method of creating objects in MAX/VIZ outlined in these tutorials is to create objects from layers. Use Edit > Copy then Edit > Paste to Original Coordinates Finally, display just those elements that are going to be used and Copy and Paste into a New Drawing.Use Drawing Cleanup tools if using Autodesk Map to simplify linear features and remove duplicates etc.Set UCS to World if another has been used.Purge the drawing of all items and nested items. The following checklist should also be implemented before starting to use AutoCAD data: Extraneous lines and text should be removed and a 'buffer' drawing used instead of a main production drawing. The correct drawing method (which is easier) produces a good looking and accurate result in 3DÄ«efore using an AutoCAD drawing for importing into MAX/VIZ only those elements that are going to be used for 3D work need keeping in the drawing. When turned into a kerb line in 3D it will look like the image below: A good example of bad drawing is the non-use of arcs in the polyline command where a curved road section is represented by a series of line segments. Remember that what looks acceptable in 2D may not work as you want in 3D and may look terrible. Organisation of all elements that are to be used in 3D using layers is vital as well as a good knowledge of clean, accurate drawing methods for 3D work. This tutorial explains the main issues to consider when drawing in AutoCAD and preparing a drawing for use in 3D work Download Sample Data Also, making the layer system easily understandable and 'object focussed' is important Keeping a handle on what elements will need to be created as single objects in 3D and which will need to be created as one object is very important. The drawing should be organised to facilitate easy import / export with MAX/VIZ.Correct layering, closed polylines created from a framework and simplified object positioning are examples of this process This means that it should be drawn in a manner that benefits both the AutoCAD outputs and the 3D outputs. The drawing should be organised and drawn so as not to compromise the production drawing.It is extremely important to prepare an AutoCAD drawing taking into consideration two main issues
