Hi

I want to model a object with 1 side straight and the other side curved, and the profile 1 is bigger while the profile 2 is smaller. (For example, a knife)

However in "Swept Blend" function I can only draw 1 sketch path, thus the result of my model becomes "2 sides curved" CryingPlease see the attached jpg).

Is there any other way to model this?

 

Thank you very much

Create two "Swept Blends" then use a void to cut what you don't want

Hi Typhoon.

 

I have tried the void, but it seems the void can not cut a "floor".

It can only cut a "family / generic model"?

Another question:

How can I model the object like the attached jpg shows, but in a better way (1 piece floor with  curved section edges)

 

Thank you

Ty's advice is still valid.

 

Cretae a sweep defined by the outside curve of this ramp.  just make it the full width of the widest part.  Then in plan, create a void that cuts the inside radius.

 

And voids will cut any Revit created object - including floora and wall - roofs - families.  You just have to make them correctly.

Thank you WWHub

I have tried Component / model in-place /"void floor", "void mass" and "void generic model" to cut a floor, but it hasn't worked ....

Please see the attached jpg.

Would you tell me the correct way to cut a floor, please?

Thank you very much

You have to create the void form correctly.  Before finishing the void, you have to tell it what to cut.  You don't want it cutting something else.
