I agree with your 1st statement. but these "rubbish" are from our clients. When I open them on corel, the straight lines are one section and curves are from circles trimmed. they are simple. i export them as dxf or dwg to autocad. Then autocad will segment them. So will inventor. I re construct in inventor for hours.
I don't know how it is in other industries, but in POP and displays, you dont mess with the clients logo. And you don't refer to them as rubbish. It's what get us paid.
So you have to design your client logos for them in CorelDraw, not just cut the profiles?
You never posted a file. Have you tried creating an ifeature for the logo then using that to cut the shape? Quite often logos have to be modified so they can be cut out from a part anyway which would lend itself to redrawing. If the source information is so bad you will find it can often be done quicker in Inventor.
Rubbish is the output from CorelDraw, not necessarily their logo. What is the definition/tolerance of the products you produce? You might find you can rationalise lost of the small curves and lines in AutoCAD before bringing it into Inventor.
"It's what get us paid."
So trace over it in Inventor and cash the check when you are done
It's handling the file within the sketch is the problem. It takes too much memory. It's not the same as extruding in autocad. (which I've been doing). It's those **** nodes.
Who said anything about extruding in AutoCAD..
The topic is nodes. I already know your suggestion. That's what Im doing all this time. I was hoping someone can come up with a quicker explanation. Something outside the obvious.
Autocad can handle the lines better. It doesn't stall. So I make my solids in autocad and bring it in as a step file. If I need to change the size, I have to repeat the process.
Doesn't sound like you have tried any of the suggetions. If you are just here to vent then good luck.
You may be able to reduce the nodes in AutoCAD quite easily. Are the profiles polylines or splines or somthing else?
Can you post an example file for others to look at?
I hope this helps.
Best of luck to you in all of your Inventor pursuits,

here's what I do for CorelDraw to Inventor:
multi-coloured logos/artwork and anything complex - export as an image and decal in Inventor (never use jpg but something lossless like png). As soon as you have multiple colour logos/artworks then it's a mess trying to deal with all those colours in Inventor, it's just not designed to deal with it. Yes, I know, a decal isn't what you're after but what are you wanting to do with it in Inventor? If it's to create renders then a decal is usually pretty decent
single-colour logos (and ideally not too complex ones) - convert the CorelDraw graphics to a ttf font file and use that in Inventor. Find it FAR easier positioning, scaling and rotating a font symbol than a sketch full of 100s of lines. To do this you need the logo as a a single object within CorelDraw, so weld/conbine all shapes together and no edges can overlap/cross, but if you know what you're doing then can create semi-complex (single colour) logos as a single keypress within a ttf font file (eg, we have the company logo, WEEE wheelie bins, CE symbols etc as a single key-press within 1 font). These then emboss, extrude, etc within Inventor (personally have found extrude seems to work better than emboss tho). If you've only got single-colour logos then I would highly recommend looking into this method.
also... remember CorelDraw has the auto node reducer which could help simplify the complexity of any artwork whether you're thinking of the ttf route or going back to dxf import.
