Helo Ryan,this plot is an intersection of 3 lines

i would like to create a 3D model out of this contour

we need to fill the line area inside and give it a 1mm width.

how can i do it?

thanks

Once you have been able to generate the contours in the program you could use a 'Fill' surface (found under 'Insert', 'Surface') to select the two contours and create a surface between them. If the contours do not connect on both ends to make a closed contour you may want to create a sketch entity to close the contour before using 'Fill' surface.

Once you have a surface you can use 'Thicken' (found under 'Insert', 'Boss/Base') to transform your surface into a solid with a thickness of 1mm.

hello Ryan i was able to draw the contour of the shape in MATLAB

could you tel me how could i plot mathetical contour in sold works?

Thanks

Hi Lina,

SolidWorks can't handle polar coordinates. You would need to run a conversion on these equations to change them into cartesian equations or output raw X/Y data points before you could plot this in SolidWorks.

no problem,i can convert into cartesian coordinated .

where in solid works i need to input the Cartesian formula?

so i would do Fill afterwards

Thanks

You would input into the cartesian equation into an Equation Drive Curve (found under 'Tools', 'Sketch Entities') inside a sketch.

Lina,

From the chart of your data it looks like the data close to x=0 is very coarse and may not describe the path enough for the program to accurately create the curve. If it has to interpolate the curve off this it may make an intersecting curve like the warning states. You may take more data points in that region specifically and see if it helps smooth the curve out so it does not self-intersect.

Assuming alpha and tau are constants, this is an equation in a plane. What is the third dimension component? Let me know and I'll send you back a model.

That's not right. This is in polar coordinates. you've plotted it in Cartesian coordinates without converting it.

To me the whole topic modelig a mathematical function looks more like a joke than a real question...

ln (0) =-infinity in

coordinate systems no matter what.**any**

The 3D plot of math function may has no sense for SW.

This is how it looks the 3D surface in Maple.

Limits for variables: 1.5<angle<2pi; 1.1<r<2pi:

Self intersection surface is shown. No way for SW to handle it, sorry.

________________________________________________________________________________________

Or, for different limits: .3<angle<.5; .2<t<pi/2:

This oscillation will crash SW at once...

Conclusion: SW is not supposed to handle 3D objects shown above (except for very narrow limits of variables).

Hi Lina,

There are two options that immediately come to mind that could help accomplish this. The first, and probably easier of the two, is to use Excel to plot this equation into cartesian coordinates (x,y) and use the Curve Through XYZ Points command (found under 'Insert', 'Curve') to plot the resulting X/Y data.

Otherwise, if you wish to use a sketch equation you would need to transform this equation into a y(x) function or two parametric x(t) and y(t) functions to input into the definition of an Equation Drive Curve (found under 'Tools', 'Sketch Entities') in a sketch.
