please help on draft angle .

[apollo]

Hi, Does anyone know how to make a draft angle greater than 30 degrees? Thanks.

The limits on the angle using the draftfeature are+30to -30 degrees. Depending on what you are doing try using extruded or revolved geometry to add or remove material.

 

[design-engine]

sweep a surface.... Thats what I teach depending upon the application.

There is atip for making a draft angle more than 30

 

[PRStockhausen]

For the example shown in Asho's pdf, I would create one datum at the required angle and use a replace surface to match it up. The result is not a combination of two angles requiring a created dimension in a drawing, but only the one dimension.

Because I have a hexagon like a nut and it's hard to revolve or extrude cut. I used blend to do this job and it looks ok. Thanks.

 

[design-engine]

I bet you could sweep one.... can you post a picture? or your model?

 

[apollo]

ok here is what i did. The hexagon on the center is swept. I can't seem to post a photos....

To post a photo you need to get the picture so it's no more than 50KB in size. Your photo was a little over at 60KB in size.

 

[design-engine]

compress it some. email it to me and Ill post it. [email protected]

its about to rain in downtown chicago

Oh... I see the zip model... one sec.

here ya go.

sweep works fine....

any angle you want.

started with a hex shaped curve geometry. Then evoked the 'variable section sweep' tool with the option 'constant section'

design-engine, thanks for posting the photo. yeah that's just another way to do it.


I forgot to mention that I used blend not sweep. Because the shapes are the same.

I guess that is what is so cool about Pro/ENGINEER... so many ways to get to a solution. There is no right or wrong way.... except for the draft tool. I think that might be the last way I would do it.

hi Apollo and Design-Engine


if the geometry's side faces are not touching adjacent geometry drafted offset tool will help.








in this we can give the dimension of the feature at bottom, height and angle.

 

[apollo]

rudresh.hm- not sure how you did that but definitely another good way! thanks.

[Asho Pulsar]

yup rudresh,we can use this feature for some cases like which you shown above...

. One good thing in this feature is we can enter angle more than 30

 

[AHA-D]

But the 30

 

[apollo]

rudresh.hm,


That's another new way I have just learned. But I noticed that it can only go up to 60 degrees, right?

true, yet the most logical solution - being able to enter a draft angle greater than 30 degrees - is not the one you can use to achieve this.

I know that the developers at Pro-E think that if you have a draft angle greater than 30 degrees then it is no longer draft but if draft is the easiest way to get an angled feature on your model why limit us in what angle we can use?

sure, there are other ways to achieve this feature but none are as simple and elegant as just entering the angle you want in a menu like draft..........
