Stages in lifetime of a model |
|
Modelling at the concept stage is generally termed as a massing model. This consists of very simple 3D elements that generally form the basic shape of a project. In the new version of XM, solid modelling and indeed Triforma solids have now become very simple with the introduction of new element handles, which allow forms to be pushed and pulled in to shape. This is extremely useful for providing a general concept and if used correctly with Triforma Parts you can easily produce colour coded plans which can be used in conjunction with a report.
As you progress in to a schematic stage you start to construct the model using the major structural elements, piles, foundations, beams columns, slabs, walls etc. The more you rely on structural elements the better your productivity will be as far as drawing production goes. Note:- Structural rules can only be applied to structural elements in this release.
With Tender and Construction models the key lies in what output you really expect from the model.
Do not get bogged down modelling elements which are of no use with regard to the drawing extractions you are planning to produce. For example concrete stairs and ramps can often cause unsightly concrete cuts due to the location of the cut plane. Often these elements are added into the plan drawings as line elements so think whether they need to be modelled at all.
Don’t go in to details that are not easily adapted to changes in situation. An example I could think of is base plates and HD bolts. There are a variety of ways in which this could be done but you need to use the method which gives you the most control over the output. That could simply be cells, references, Dimension Driven Cells etc.
Another main key to modelling is control over the model to allow you to have the option of what is included in a drawing extraction and what is not.
