This is tutorial number 20 and it covers how to use construction geometry within

KT-A-V5. To start off open up a new KT-A file and once you've done that let's

go into the sketcher. So let's click sketch and click the front plane. Now the

construction geometry tool is going to be this here on the sketch tools. So what

construction geometry is is that we're able to create sketches and from those

sketches we're able to convert them to construction geometry. Now the difference

between a construction geometry and a normal sketch is that the construction

geometry will have dotted lines and the construction geometry when you go to

create a part will not be included in the overall extrude or cut or whatever it

may be that you're doing with the feature. So construction lines are just there

strictly to kind of make dimensions and kind of make references off of. So to

start off let's draw a few profiles so let's make a circle and let's make a

line from the top of the circle to the bottom of the circle. Now to convert a

sketch to a construction geometry what you have to do is select the line and

click the construction. As you can see it has the dotted line now and that's

construction geometry. Now we can still dimension these so let's dimension this

construction geometry. Let's turn it to 100 and now we've made the construction

geometry 100 and it's also relating to the original drawing and the original

drawing the diameter is now 100 also. So if we were to go and extrude or use this

sketch as a cut only the circle would be used. The line that we use is the

construction geometry would not be used at all. So when you have a sketch or a

profile if you have a bunch of other lines that are just out at the side you're

able to use those as construction geometry. Now you're able to either select a

line and turn it into construction geometry like we did the first time or if

you toggle the construction geometry on every profile that you make is going to be

a construction geometry. So there's a couple different ways of going about it and

you can turn it back from a construction to a regular drawing. So construction

geometries are sketch parts of a sketch that will be used to make references and

are part of the construction of your overall sketch. At the end though you don't

have to delete them or anything. They can stay in the sketch but will not be used

when you create a feature. And that concludes our tutorial on how to use the

construction geometry feature within KTAV5.
