I am running CorelDrawx6 and the trial version of CorelCad 2017. When I attempt to extrude a rectangle with rounded corners and some holes in the middle from CorelDraw to CorelCad I receive the error "Sweep created a surface with parallel u and v «Error»". The circles, if selected separately, will extrude, but i cannot create a rectangle with holes in it. My purchase of CorelCad would depend on this procedure running smoothly. The Imported .cdr/.dxf files are defined as splines in the CorelCad properties docker and the Explode/Explodex commands won't convert them to polylines as per another answer I found on the forums. I joined the Curves in CorelDraw with zero gap so the line is continious when selected in CorelCad but the properties bar tells me they are not closed.
Would upgrading to Coreldraw 2017 resolve this issue for me?
Thank you if you can help me.
Peter.
Hi David,
Wondering if you could possibly elaborate a little on how to do this? I am having the same problem and no matter what I do, I get that same error on most things. I even tried to emulate the tutorial located here: https://youtu.be/VCz-iZUX6JA
I drew my own gear using the exact same method in the video, but it doesn't work like it does in the video. The only thing that will extrude is the circle in the middle.
I've tried using the PEDIT command, but can't get it to do anything with any of the lines. I've tried Exploex, but can't get that to do anything either.
I am using X8 and CorelCad 2017.
Thanks.
Yep, I can't get any of that to work either.... Not in any version of CorelDraw or CorelCAD. Hopefully Klaus will come along and comment on how to make it work. It would be nice if CorelDraw objects were recreated as 2D meshes, but I don't think they are :( Instead, they come across as some other kind of object, and while it works well in 2D, it's not so good in 3D. A shame really as all you need for a polyline mesh is a vector outline. It's not even that difficult to import Excel databases of points into CorelCAD. Generally, if I need to do anything with CorelCAD, I usually try to do it entirely in CorelCAD. Creating a gear in CorelCAD from scratch is so much easier than with CorelDRAW... But if it's art, well, I've never really had to import anything that complicated.
I'll let you know what I find and if I find a workaround.
I have no idea what they are doing in that video. It seems edited and too much is missing.
David
Depending on the line or curve drawing tools you've used in CorelDRAW the shape might be imported as spline.
That was the case with the artistic gear sample in the video. In order to transform such a 2D shape into a 3D solid, you can do the following:
In some cases, you only need to perform one of the above suggested transformations to make the 3D operations work as intended.
For achieving a hole in a (3D solid) shape you should
With regards to the CorelDRAW design sample in the video, please note that the text was converted to curves before importing the CDR file in CorelCAD for the 3D operations.
Hope that helps.
Best regards,Klaus
Yes is does import as a spline. Is this the correct place to tell me if it's open or closed? It was certainly closed in Draw, and all point seem to be connected it I move the points, but specifically what am I looking for in the properties palette? This came in marked as yes.
Explodex certainly turned it into a polyline. I just left precision at default of 10 for now. After using Explodex, that same box for open or closed, now says No.
This was marked as no. I changed this to Yes. Is this what you mean by making sure it's closed?
If I try to extrude now, I get the "Unable to extrude the selected entity" error.
So the only portion of your instructions I have not done is convert the polyline to a region. I am unfamiliar with this. Could you let me know how to do this? Hopefully that's the step I'm missing.
Thank you for your help with this. I assumed since both programs are Corel, it would make getting vectors from Draw to Cad intuitive. Basically the only reason I purchased CorelCad. :) Oops.
Thanks for your thoughts David.
It never dawned on me to test out bringing vectors in from Draw in the trial. I mistakenly assumed that since they are both Corel, that would be well integrated. Lesson learned I guess. It's honestly the only reason I purchased it.
I really wouldn't ever design a gear in Draw either, but there are a lot of things I would use. I've been using Draw for something like 20 years, and there are so many things I could do faster and easier. Much of it is for artistic purposes. Things that are not possible or very difficult to do in CorelCad.
Definitely to much edited out of that video. Seems they should have shown the important parts of making that work. I am certain I am not the only one that got CorelCad because of their experience with CorelDraw. Seems they should have an entire tutorial section on using CorelCad with CorelDraw.
Seems to me CorelDraw should have an export to CorelCad option that makes sure everything is compatible instead of just using the cdr file. But what do I know I guess. ;)
