Hi,

 

I can reproduce the issue, but (whithin just a few minutes time) I don't have an idea why the inner circles are not excluded from the 3D-Solid object after running _PRESSPULL.

Interestingly AutoCAD generated Region objects from the circles, but then they are not used at the end of the command to be subtracted.

 

For now, so you can continue to work: extrude the circles with a height > the previous 3D-Solid object and then use command _SUBTRACT to get the holes created.

Hopefully anyone else has an idea about the reason why _PRESSPULL fails in this situation.

Hi,

 

your two shape just need to be FLATTEN,put them at plan top view then use FLATTEN command. then you can PressPull it as you wish.

 

Command: FLATTEN
Initializing...
Select objects to convert to 2d...
Select objects: Specify opposite corner: 60 found

Select objects:
Remove hidden lines? <No>:

Hi,

 

be careful, command _FLATTEN destroys the splines (by converting them to polylines), that means you lose a bit of accuracy.

hi thanks this worked and the presspull command is working, however i have another problem with another command now lol, ive mad a surface using the patch command and have attempted to use the sculpt command to convert it into a solid but it's saying there is no water tight volume yet it clearly is, i'll make another thread about it but if anyone could help me out with it here that would be great, attached file, on the right is with a surface on the very bottom and is flat, on the left the surface is raised on the z axis by about 0.01 to ensure and intersect, and the object group on the right is what the patch was made from

noted, though i think the level of accuracy in this isn't that important as the model is only going to be about 60-70mm long and 50 mm wide with the material being petg or pla for 3dprinting or vacuum moulded acrylic.
