3. Boolean Solids Tutorial Introduction The CADMAX Solid Master Tutorial is a great way to learn about the benefits of constructive boolean solid modeling with CADMAX We have assembled four typical parts that you will be able to construct using CADMAX Solid Master Each part should take between 20 40 minutes to complete The tutorial assumes that you already have some familiarity with CADMAX In you are unfamiliar with CA DMA X review the Getting Started section first H ere are several additional suggestions before getting started In the tutorial there are several conventions that are used with text The text Draw gt Circle gt Center Radius means to click on the Draw menu hold the cursor over the Circle function until the Circle sub menu pops then click on Center R adius When you see a statement that starts with the word set this means you are to set a modifier value in the currently displayed Function box For example in the Line function box you will see a Connect modifier When you see the statement Set Connect to off this means you should set it off by clicking on the word Connect if it isn t already off Sometimes you will be asked to set a specific value for a modifier For example in the Circle Function box you will see a modifier called R adius with a combo box below it and a history arrow When you see the statement Set R adius to 25 this means you should click in the R adius text field and
