Learning Objectives

At the end of this class, you will be able to: Know the difference between predefined templates Know how the basic 3D modeling tools work Structure a family from the ground up Build a basic family the right way

Parametric or not?

Always parametric 3-5 types Everything is possible Should we?

Templates

Family categories

Many different categories Choose the right one Beware/ Be aware of Mass and Profiles Built in/Hardcoded parameters Subcategories

Hosted Families

Be sure Know the different hosts Learn the little ”quirks” of different hosts.

Which hosts exists: Facebased Floorbased Wallbased Linebased Roofbased Ceilingbased Patternbased

Predefined templates

Ships with many different templates Templates ”lock” objects Start with a ”Generic Model” template Once you choose a hosted templates you are stuck there

Blend

Two different closed loops of lines on different heights

14

Revolve

One or more closed loops of lines that ”revolve” around an axis line

15

Sweep

One or more closed loops of lines that follow a path in space 2D or 3D

Voids

All of the above but acts as ”Antimatter” – It subtracts from the solid

Which parameters do we need?

What does the I in BIM mean in this family? Geometry driving parameters Non geometry driving parameters Type or instance parameters Naming convention

Referenceplanes

Skeleton/Bones Referenceplanes becomes workplanes if you name them Draw similar planes the same length Set ”Is reference”

Strong/Named Weak None

Define origin (Insertionpoint) Know your size

24

Dimensions

Place dimensions strategically Do not overconstrain EQ adds ”Automatic Sketch Dimensions”

25

Parameters

Naming convention Group smart Instance or Type

3D Geometry

Set correct workplane before you start Lock to referenceplanes Use align if you have a complex family Set Visibility Set Subcategory if applicable Set Material if applicable Don’t forget to lock in all 3 dimensions

27

2D Graphics

Temporarily hide all but referenceplanes Draw with symbolic lines Will show up in views perpendicular to the one you use For 3D lines that show up in all views use ”Model Lines” Change ”Reference” Set correct ”Subcategory” Set ”Visibility Settings” Know what ”draw in foreground” means

28

Materials

Do not fill your family with unnecessary materials Load into project and set materials Save out from project instead
