    Posted: 04.May.2017 at 03:29

Hello All

 

I need your help for this isuee.

 

Here is what I want to make as 3D.

There is chamfer 1.66mm x 1.66mm.

I tried this.. but Autocad told me "Error ,Blend failed.. "

but I do not know why at all...



Here is starting point.

First, I draw this line with Adobe-Illustrator. and output DWG file.

and Open it....




I tried with 3 way.

 

1) With Chamferedge  --> failed.

2) With Blend only.. ---> failed...

3) with Sweep --> failed.


I hope Someone tell me why Autocad can not draw this simple shape..

Is this limitation ???

 

Could you help me ?? 


here is cad file

 uploads/724730/shape1x.zip



If AutoCAD is not possible to draw it,

How should I do ? Should I buy other CAD software to draw this only ?


David.

I have had time to open/view your drawing.  You could try using AutoDesk A360.

Well if you're more concerned about the end result (may not fully satisfy your requirements however) rather than the process I was able to achieve the following.  It was somewhat involved.  Maybe someone else here with better skills can arrive at a solution with less work.  And, yes, it is a 3D solid.  I checked.

Thank you , John.

It is good : )
I want to learn your step with AutoCAD.
I tried many time "Chamfer" -> Loop -> Select some edge -> 1.6 -> 1.6 -> Enter
CAD refused to make chamfer with  same error.

Failed to perform blend.
Failure while chamfering.

How to avoid this error ? Please have me to learn your skill....

I did not use chamfer.  I basically used a series of profiles that I lofted separately then unioned them (there were three) together.  But first I had to use the SPLINEDIT command and turn the outer spline into a polyline.

Thank you , John

I also make it with LOFT + some guides.
but It is not beautiful than I expect.
There is lot of NOT good surfaces.. 
This maybe limitation of AutoCAD



Anyway, Thank you !
I will try other software too.
Is there any recommendation ?

I'd try either A360 or Inventor.

Sorry about late reply, I hope it will help... That's not a limitation of autocad what you said, I think your model suffers from bad junctions, or curves in the model. "Cannot blend" error is usually connected with inaccuracies in your 2d shape, for example 2 curves  are not perfectly blended with another curve/line(tangent)  between them. You should do a little "repair" of your curve exported from illustator - fillet the straight lines with radiuses so it gives a perfect blend or flow between the curves.
Even if you managed to get polyline from your closed shape or a region, that does not mean the CHAMFEREDGE command will work if curves are "badly" joined.
Sorry I cannot open your attached file because I use ACAD2015.

If naka hasn't fixed the problem by now (some 14 months later) then he had better change careers.
