Do you lose dimensional accuracy when copying a profile from AutoCAD to solidworks?? Example a perpendicular in ACad becomes 89.99999999998 degrees when brought into SW. Any experience with this? Any comment appreciated. Cheers!
AutoCAD and SW use different "kernels" to do the math for the geometry, 2D and 3D. so yes, there can be rounding errors when going from one to the other. it is usually good practice to use fully defined sketches in SW - this would usually require the addition of sketch relations (vertical, horizontal, perpendicular, etc.) when copy and pasting from another source.
I use copy and paste for that, then apply dimensions and constraints until the sketch is fully defined. Eliminates all those tiny errors.
If I dont care that much I copy, paste and fix all entities.
I’ve pretty much given up the copy/paste from others… fixing their problems takes longer than doing it right yourself.
I would agree. But you have to deal with project managers that question why your re-sketching something that has already been "somewhat" defined in AutoCad.. It's a political thing.
That is the answer I was looking for... I suspected these conversion errors, and I define sketches religously (A petpieve of mine when I receive a model with blue lines everywhere). Thanks for the comment Jeremy.
how come I cannot copy and paste an sketch from AutoCAD,
we recently updated to a new computer, I used to use it very often now I can't
Is there any specific configuration in both SW and AutoCAD to do it?
Try using DraftSight (free software for DWG/DXF Files) to open your DWG/DXF files and then try copy paste from there else edit the files and remove the portion/entities you don't need. And then import into SOLIDWORKS.
