Problem with drafts

[Jacoolo]

Hello



I met some problem while modelling with draft. Look on picture below

This inner shape I wanted to draft. It quickly apeared to be not
possible. Only the not curved surface from were drafted. After that I
got a problem in the place that simple surface meets curved one

Do You have any idea how to do that. I suppose this curved surface is not able to be drafted.

I tried to make a model similar to yours, but it works fine to draft on. Could you upload the model or an example that behaves in the same way. Also describe the angle and hinge you want.

 

[Jacoolo]

it will be hard to upload because it is a product of firm where I work.
The hinge I used was te surface at the top. I wanted to draft these
both surface- curved one and not curved, and it failed.

 

[arroyopr]

are you trying it like this, first select the surface to draft then go to reference and select the surface to hinge

unless the botton surface blend to the top i don't see any problem with the draft.

Thanks arroyopr but it is not exactly like this. The example is good by the hinge is wrong. In my case the hinge should be the surface normal to Yours(in the right side). Try this and if it will end up succesfully give me a sign, because I have still a problem with this draft.

 

[arroyopr]

you mean the surface that's parallel with the draft surfce. if that the case i think that's imposible becuase it has to be perpendicular. or like this.
