Hi all,


I'm new user. last year go to tarining already but forgot to draw piramid.


Any bady can help me?

Hi, one easy way is to use the feature "Blend"


You need two sections, first one you sketch a square and just a sketched point in the second.


When you have made the first section in the sketcher, scroll down the sketch menu and pick "feature Tools" then "toggle". That will start the second section.
Pro/E will prompt for depth between sections when you leave the sketcher.

another method is touse the draft feature

I dont think the draft feature let you remove an entire surface as in this case (assuming you apply it on a cube), but I've been wrong before...

draft will only allow 30 degrees. draft will allow you to remove an entire surf (top of cube) but you have to calculate the exact angle. if you make it taller you will overlap and fail, if you go shorter then you will have a flat top and not a point.

Another method is chamfer -AngXD and select all four edges of the cube. This also we can do but blend is the best feature to create a pyramid.

another method.... Just for academics...

. Variable section sweep with Graph (i.e if you want to control the blend.


Ah yes... as I remember (I have a weak memory

), if you are using a blend feature, the start point is important. else you will get a twisted blend.

Start point of the first section...doesnt matter...

coz all corners pointing towards one point. You can give any corner of the sketch as a start point... reverse or forward direction.

here is an example of a piramid or tetrahedron

Why we forgot the simple Sweep command...

Not quite right.... If you do not choose the start pointcorrectly you will end up with a twisted piramid as below. In the example below, the bottom rectangle was drawnRIGHT to LEFT and the top rectangle was drawn LEFT to RIGHT with default start points.

In my case i did blend feature in that I put "rectangle" as a bottom section and a "point" as top section. Only for this case start point is not mandatory.

oH... OK...
