help with extrude on d roof

I've tried my best to follow the steps on the above re. developing a roof 3d drawing from a plan.

 

I develop a polyline for the roof plan

I extrude the roof plan using the taper option with a 45deg. angle

I move the 3d face up to what i think is the correct dimension but I have no success...

Modeling Operation Error:
No solution for a vertex

 

I'm obviously not understanding this correctly. The strange thing is i can get it to work on a simple square roof plan with 4 hips...

 

Any help appreciated.

Couldn't let this get the better of me....

 

Have been experimenting and it appears the proximity of the model to the UCS origin makes a difference (experienced this with hatch patters before). Moved the model to 0,0 and all appears ok.....

You extruded the roof beyond the sloped angle.

Attach your drawing here, let's see.

thanks for the reply,

 

In the model there are 2 plan profiles. As you can see I have done it on the 4X4 model, I have done it on the 8x4 model (twice but can't repeat it a third time)? On the cross profile I have not been able to complete it.

 

Methods used;

 

extrude, tapered angle 45, heigth 2000.

 

I have also tried extrude, ta 45, h 1000 and then move 3d face 1000.

 

Where am I going wrong?

I gave it a try and you're correct, it gave unexpected result.

All of the ridge lines not converge at 1 identical point.

Go to paperspace to see the unexpected result.

I did started a new drawing and drew it at 0,0,0 but the result was the same, maybe my 2008 is crappy.

Glad you found the answer.
