How can I define my marquee to be more specfic in warp tool

[daiyuyang]

I use Creo 7.0.2 on Win10.

Here's what i encounter:

I want my body to be 1.5 times high by stretching in warp tool, but the result didn't match. it turns out to be 2.1xxx times. and I found out that the boundary of the marquee is not lying on the surface of my body exactly but having a offset value.

Size:150x43x1.5mm File_name: tmp_warp.prt

So when I stretching the result won't meet what I expected.

*This body forms by removing certain features.(The original one is the shape defined by my customer, and therefore I can't show you guys.)

However when I create a new part and draw the same shape but big hieght, the marquee correctly lies on the boundary of the body.

Size:150x43x30m File_name: tmp_warp_2.prt

The question is for the case I encounter, I don't even know the offset value of the marquee, so i can't adjust by modifying the value in the box.

Is there any possible ways to snap the marquee on the surface I want or know the offset value so I can adjust it.

This model (Creo 4) increases the thickness from 1.5 to 2.25 mm as specified using a scale of 1.5. I have used absolute marquee size to adjust it for this case. You will need to evaluate how to manipulate it based on how your model is built.

In your example there are more readily implemented features to control the thickness, in general I would not use warp to control geometry of a part. I would only use warp if there is no other way to manipulate the geometry.

Thank you. Solved

And I found out another approach by adding body as reference,

but the tricky point there is when you choose body as reference. the marquee might not lie exactly on the boundary of the object for the directions other than the one you are going to stretch. it sorta make no sense to me, but, in this case, it dosen't matter.
