Which tools do you use to draw Conic Curves ?

Hello Edgers,

 

Solid Edge development would like to know which tools do you use to draw conic curves?

 

We would like to know the following –

  • What/where is the application of conic curves in your industry ?
  • Which conic curve is used more Parabola/Hyperbola/Ellipse ?
  • Are asymmetric curves used? (Start point to shoulder and endpoint to shoulder(shoulder is the highest point of the curve) are different lengths
  • Which features would you like to use conic curve with - example extrude, revolve, sweep ?
  • Which of the following inputs are known when creating the curve –
    • start point
    • end point
    • focal point – if yes, is it used for positioning / constraining the curve?
    • vertex
    • shoulder (Image – conic curve attached in mail)
    • rho value – what is the value that is frequently used?
    • anything else
  • Which of the above point is most frequently used?
  • Which of these would you use to edit the curve?
    • start point
    • end point
    • focal point – if yes, is it used for positioning/constraining the curve?
    • Vertex
    • Shoulder (highest point on the curve)
    • rho value – what is the value that is frequently used?
    • anything else
  • Do you import conic curves to Solid Edge.

 

Please reply here or you may drop me an email at mehta.rutuja@siemens.com with your responses.

 

Thanks,

Rutuja

Hi @Rutuja_Mehta 

 

 

the question, which is coming in mind when reading Your post is:

"What will I need such a curve for?"

 

All Conic Curves in reality are sections of a cone in 3D.

So why should I create it manually as 3D curve?

I do not see a big need, neither immedeately after reading the question nor after thiniking about a minute.

 

TBH I think there are more issues on the list for solving than having conicle curves, isn't it?

 

 

regards
Wolfgang

@Rutuja_Mehta  I'm excited that you're hear asking for input so I hate to report that I'm with @hawcad on this.  I just don't see that I would use it much.  I'm trying to think when I would need it, but I understand maybe others will have a need and hope they chime in.  I see the ellipse sketch element, but had to open a sketch to check that it was there, I just don't use it much.

 

Other thoughts:

  1.  I haven't needed it yet, but I do read threads where people are driving curves from excel or some other table.  Maybe those topics would guide what is needed.  If they are using a table for the same type of task repeatedly then maybe that type of curve as a sketch element would be handy.
  2. I use the helix and spiral curves frequently, I find it unfortunate that they are hidden in the surfacing toolbar by default, but once a person knows where to look it's ok.  For I while I thought it would be in the 3d sketch environment.  Pretty much any spring or wireform that has spiral or helix to it I start out with the "Helical Curve" command, then build other sketches from that, derive a curve, then surface, then thicken.  I've found it to be the most robust when updating/editing.
  3. I frequently wish I could just get an involute curve from an arc or circle.  I beleive it would be best if it were a generated sketch element, but being a feature like the helical curve would have it's benefits too.  I would use the involute curve more than conic sections. 

Again, that's just based on my limited usage patterns.

Hi,

I understand your question, but I don't think that this is the good direction. I think we need a "general feature" not special feature to draw a parabola, an other special feature to draw a hyperbola and etc...

The general feature name is Equation driven curve.
All of our competitors has...

Guys, this feature gives more flexibility to customers against parabola, hyperbola drawing features.

@Imics Assuming you mean "Equation Driven Curve"...

@Imics I think your edit broke your link.  I like the idea you proposed.  Include formulas from a drop down for standard shapes (like conics) and provide the ability to locate the generated sketch relative to other geometry.

Hi @Rutuja_Mehta ,

 

First of all, I really appreciate that you and developer team need for our feedbacks. We've already discussed about and you can collect lots of useful infos:

Exactly what I was thinking about when I mentioned driven curves. Also, good point about user macros and add-ins. If there's an add in that is shared with the community and it is popular, then just incorporate it, buy the IP whatever. Remember when polygon was a VB macro add-in because it wasn't an option in sketch commands? Without knowledge of that, polygons were drawn manually in Solid Edge.
