Creo Tutorial for Beginners – 7A | Creo Pattern vs Geometry Pattern | Creo Axis & Direction Pattern

In this series of tutorials we are learning Creo from start to finish in this current video we will learn pattern concept in detail i request you to watch this complete video to understand pattern concept perfectly if you want to receive new video notifications every alternate monday wednesday and saturday then please subscribe to this channel.

And press the bell icon please also like and share this video let's start with this tutorial if we click here on this arrow below pattern you will see that there are two patterns one is pattern and other is geometry pattern so at first we will understand what is the difference between pattern and geometry.

Pattern when you select any feature you want to pattern the command shown here is pattern and not geometry pattern so you will see that the difference is given in this help also this pattern creates instances of a feature feature means single feature so you cannot.

Create pattern of multiple features using this pattern command whereas if you use geometry pattern you will see that it can create pattern of multiple features as well as of surfaces and curves let's see here if i select this single feature it will show pattern command but if i select multiple features suppose if i.

Press ctrl and select this extrude1 also so here you will see that that pattern command has been removed because regular pattern command is useful to create pattern of single feature only and if we take our cursor here you will see that the geometry pattern is still active that means you can create pattern of multiple features using geometry.

Pattern so that is the first difference then geometry pattern regenerates more fast if you have very large pattern of 1000 or 2000 features then it is recommended that you use this geometry pattern because it will regenerate faster compared to pattern command then when we create pattern using pattern command suppose if i select this.

Extrude2 and click here on pattern so here you will see that that extrude2 is included in the pattern and it is not there in model tree suppose i will just create one pattern quickly so that we will understand that concept perfectly suppose i will create quickly one axis pattern so here you will see that that extrude2 has.

Been included inside this pattern so it is not available if you want to use it for any other command and suppose i will just cancel this pattern then we will again try creating pattern of this extrude2 using this geometry pattern so here you will see that Extrude 2 remained outside of the geometry pattern suppose again i will.

Quickly create one pattern so that you will understand that so here you will see that this Extrude 2 remain outside and it is not the part of the geometry pattern and you can use that feature for any other command so i will just undo it so those are the difference between pattern and geometry patterns now let's.

Start creating some pattern now here i have created one simple plate and i have created one hole using extrude command so here is this plate and this is the hole so both i have created using simple extrude command now here suppose i want to create pattern of this hole in number of rows and number of column.

Format so click here on Extrude 2 if you want to use pattern command you can directly click here and if you want to use geometry pattern then you will have to click here and click here on geometry pattern then here you will see that first option is direction so this direction is useful.

To create rectangular pattern so here it is asking for select one item so here it is giving in detail select the plane flat face linear curve coordinate system axis or axis to define the first direction so using all these items you can define your direction suppose i will define direction by using this line so i will just click here on.

This line so here as per this line this direction is defined then here you will have to define number of members in the first direction that is number of items suppose it is 5 and press enter then here you will have to define gap between those items suppose it is 60.

Enter then if you want to reverse direction then for that you will have to click here on flip the first direction so just click there so that pattern will be created in opposite direction so again if i click here on flip again it will create it in this direction then if you want in single direction only you.

Can directly click here on ok so that pattern will be created and if you want to define second direction then you will have to click here to add item so just click here so from here this second direction parameters are starting then i want to create pattern in this direction so again i will click here on.

This edge so here second direction is defined again now this second direction pattern is created in this direction suppose i want to create this pattern on this side then for that you will have to click here on flip the second direction so here now pattern is getting created on this side.

Then again you will have to define number of items suppose it is 5 enter then again here you will have to specify gap between items suppose it is again 60 enter so here this rectangular pattern is created then if you don't want to include some members in the pattern then you just have to click on them so the items which.

Are shown by white color will not be included in the pattern just click here on ok so here pattern is created and here you will see that those items has been hidden and if you want to include those items also then for that click here and click here on edit definition.

And again click on those dots those white dots so once those become black that means those members will be included in pattern then click here on ok so here that pattern is created so in this way you can create rectangular pattern next we will learn to create circular pattern so what i will do i will just.

Remove this pattern so just right click on it and click here on delete and click on ok so all the items will be deleted then for circular pattern i will create one cylinder so click here on extrude then select this face then just right press that means you will have to just press and hold right button of your.

Mouse so in creo in the place of right click you will have to use right press so that means you will have to press that right button for some seconds then click here on circle or you can also select circle command from here suppose i will click here then specify center point take your cursor away and click.

Press middle mouse button then again right press and okay and specify height suppose i want it 200 enter and okay so here the cylinder is created then i want to create one hole for pattern so again click here on extrude and.

Select this face then again right press click here on circle and specify center point here take your cursor away click then again right press ok then click here to reverse direction now here i want to create through hole so click here.

And click here on extrude to intersect with all surfaces then click on ok so here through hole is created then i want to pattern this hole so again click here on extrude 4 suppose this time i will use this pattern command click here on pattern then click here click on axis so for.

Circular pattern you will have to select your axis then you will have to define one axis again for axis you can use datum axis or coordinate system axis that means either you can select this x z and y axis or you can use any center line axis so here while creating cylinder this axis.

Got created automatically so i will select that axis so here array is created for four items so i want it to be eight items so here i will make it eight enter then i don't want to define angle between those items but i want to create pattern in complete 360 degree.

So for that you will have to click here on this angle symbol and you will have to define your angle to fill so right now my angle to fill is 360 degree therefore it has created pattern in full 360 degree suppose if i want to create half pattern then i will have to define here angle of.

180 degree enter so here those eight items has been filled in 180 degree and if you want these items on the opposite side then from here you can flip it just click here on flip button so here pattern is transferred to other side so i want this pattern of 360 degree.

Enter then if you want to further create this pattern then here you will see that there is direction 2 so here is direction 2 here you can define number of patterns in direction 2 suppose i want it to be two enter then here you will have to define gap between those two items suppose it is 50.

Enter then click here on ok so here that pattern is created actually the gap will need to be more so that they will not merge suppose we will change that gap click here click on edit definition and suppose we will make it 70 enter and click on ok so here that pattern has.

Been created perfectly or if you don't want this second direction you can also remove that click here click on edit definition and from here again you will have to say one item enter and click on ok so here perfect circular pattern is created.

Then when you use pattern command in place of geometry pattern then as we have seen that feature gets included in this pattern so while deleting the pattern you will have to take care so when you right click on pattern which has been created using pattern command and not geometry pattern command.

Then here you will have two items one will be delete that means it will delete both the feature and the pattern and if you want to keep the feature and delete the pattern then you will have to click here on delete pattern so it will only delete pattern and it will keep that feature using which we have created pattern so just click here on delete.

Pattern so here extrude 4 remain as it is suppose i don't want this cylinder and this hole so i will just select it right click and delete okay so up till now we have understood what is the difference between pattern and geometry pattern and we have also learned to create rectangular pattern.

And circular pattern so there are some more pattern types so here you will see that there are further more patterns types like fill table reference curve and point so all these remaining patterns we will learn in next part of this tutorial so please like share and subscribe thanks for watching we will again meet in next.
