Basic curves 2

[vishnuvardhan0058]

Hi all,

Why some of the companies use basic curves for modeling components, why con't do it in sketch.
Please give me answer...

I believe that this more a personal option than a company policy!

lack of knowledge (my personal opinion)

I fully agree with Jerry!

I met designers that complain about using Sketching, pretending functional faults of it.
They use curves, points, planes meaningless, creating confusion for future users.
The reality is that not everybody is ready to invest time in learning a new tool (Sketcher in this sample).

Last day i had a telephonic call from one of company they are asking for professionals who have expertise in modeling through basic curves.
I dont no how we can edit the drawing if we go for basic curves modeling...

Dear All,

Interesting topic. I am against usage of sketches. It has its own advantages.

I personally use basic curves because it gives more freedom in editing Specially in case of freeform surfacing where you need to create many help surfaces to get a final surfaces and it keeps my model tree shorter and easier. Sketches because of constraints are lot more difficult to handle in these cases.

I prefer sketches when modelling parts with basic shapes.

Hi desgur,

Please provide me some tutorials or examples showing modeling with basic curves as i want to learn about this.

We make mold using 3d imported from the costumer,
Make the sketch for us is wasting time.
I think use sketch depend of what kind of work you are going to do.
And often we remove parameters from the model.
Because the model become big (over 500mb in many case), and if we need "parametrize" a part of mould with synchronous.

Different tools for different jobs.

Both methods are still fully parametric with the solid. NX sketching, from what I remember, is a little tricky in getting the geometry constrained to the datums. The Sketch itself is easy to constrain. We had a requirement that all sketches be placed with the lower left corner at 0,0, so all dimensions were a 'positive' direction. This was for ease in laser cutting the sheetmetal parts.

I use both sketches and "curves (splines)" together, I find that using sketches to attach my splines to when I'm surfaceing makes it very easy to make controlled edits to the model. I use them all over the place as you can see in the attached models.
