Hi

I am having a small problem when am trying to extrude a face on a solid. The mysterious thing is that after removing the face and wanting to extrude it aligned on other solid, my side where I extrude that face makes an angle and should not.

Any suggestions on how to solve the face extrude problem and maybe a short explanation why that is happening?

I am not sure I understand you. Did you remove the face before the extrusion?
Here is the way I work:
I switch the shademode to wireframe.
SOLIDEDIT > F[ace] > E[xtrude]
Now select the face. If by mistake unwanted faces are included in the selection set do not move the mouse. Hold down the SHIFT key and click again in the same place. Sometime the wanted face is under an other one and can not be selected directly. You may use 3D ORBIT ( :) ) to bring it up OR you may use a little trick: click the boundary of that face. Because the boundary is common to two faces you just selected booth of them. Hold down the SHIFT and click the boundary of the unwanted face but in a point that is not common with the wanted face boundary.
After the selection is OK enter the height of the extrusion and the taper angle. The extrusion is normal to the surface. If you need to “tilt” the results of the extrusion try to use the MOVE option of the command (SOLIDEDIT > FACE > MOVE).

Fuccaro,
Thank you for replay. I went thru all the operations you described and did the right thing. The wanted face just make an angle when I extrude it and do not know why.

I used before and went well. Now I do not know why the extrude face makes an angle.

Let me put it another way. What is the difference between EXTRUDE FACES and MOVE FACES?

check your ucs location & orientation, sometimes this can affect the direction.

This may be a silly reply but here goes.
In wireframe, select an orbital view rather than a standard iso, this should allow you to pick the relevant feature/s you wish to extrude.
It sounds as though you are probably missing a base pont or line when selecting, thus creating a wedge rather than a box.
I tend to create polylines when extruding is required, you only have to select one point on that line to extrude the whole surface.

Just my 2 bob's worth.

Thank you for answering me. I think is hard to explain some things about autocad in words.

On one of the solids I used MOVE FACES and went in the right direction aling the path ( red color).

Right under that I used EXTRUDE FACES and as you can see it makes an angle and not join the path.

I am asking my 100 points silly question: what is the difference between the two commands and what is the explanation why when using extruding faces goes as showed.

Sorry for multiple post.

Here is another exemple of Extrude Faces on a solid and went well.

I used to extend the solid ( yellow). It looks as it should. Why when using on the other drawing it makes an angle?

I am very sorry for bothering you but really have to understand how this misterious commands work and in what enviroment :wink: .
