BASIC DRESS-UP FEATURES

LESSON II : DRESS UP FEATURES12

Although technically not a Dress-Up Feature, POCKET is a tool that is used often. Unlike HOLE, the feature to PUNCH must be defined in SKETCHER mode since it is user defined, not just a hole.

pocket

13

The first thing to do is pick the face that you want to pocket the void through, then pick Sketcher

Line is picked

14

In Sketcher, pick the proper shape icon from the Primary toolbar, and sketch the shape ON THE 3D PART represented in sketcher. Once this is done, EXIT sketcher to return to 3D mode

Notice that the shape that will

eventually become a hole in your part is represented in the

part tree as Sketch2

Sketched circle

15

This is how your part will look once you have returned to 3D. The sketch you made will appear flat on the face you chose. If it is not orange, choose it to make it active and ready for pocketing

Now click on POCKET from the Sketcher Based Features toolbar

Notice that in our 3D part the sketch we

made was not orange immediately when we returned to 3D mode. NO PROBLEM.we just need to either pick it manually from the

object we are creating, or directly from the

parts tree.

With POCKET picked, the POCKET DEFINITION input box will appear. Input the desired information and Catia will show you a dashed line sketch of your pocket. If all the information is correct, push APPLY and hole will appear in 3D, then push OK to make it permanent.

Notice POCKET1 is active on the

action tree.

17

From TYPE, you can enter a dimension or constrain the depth of the punch by choosing up to next,up to last,up to plane, etcusing the arrow.

Depth is where you enter the dimension for the depth of your pocket.

Click on Mirrored extent to mirror or send your pocket in both directions.

Since Catia automatically sends your pocket in the most logical direction, if you want it to go the other way click on Reverse Direction.

Here is your part with your pocket in it. Now lets begin to DRESS IT UP

Dress Up Features toolbar

19

A close up look at your DRESS UP TOOLBAR shows that it is ready to do five basic functions for you

Fillet

Chamfer

Draft

Shell

Mirror

DRAFT is what you use to angle the

sides of your part in preparation for possible casting

processes.20

The first thing we will do is FILLET. Pick the face that you wish to fillet, then pick fillet from the toolbar. The Edge Fillet Definition box will appear, which you will fill in with the appropriate info. RADIUS is the size of the fillet and OBJECTS lists the number of faces that you are going to fillet. The box also allows you to pick the propagation of the fillet (Tangency is the best for now).

Orange means it is picked

Noted on the tree

21

You dont have to pick an entire facea single edge may be picked instead. To pick MORE than one edge, but NOT and entire face simply hold down CONTROL.

Here we have chosen two different edges using the CONTROL buttonnotice the

edges you choose turn red. MULTIPLE faces

can be picked the same way. 22
