Autocad, issue with cutting a hole, using presspull

[Anonymous]

So, I am trying to cut in the building 2 holes, using presspull command, from a drawn rectangle, adiacent to the wall I want to cut. Do not know why, but it extrudes instead of making a hole I have tried with substract and also tried to use explode (this one removes textures of the extrusion). If anyone can help me would be very appreciated I am struggling for a few hours, but the problem still persists and its very annoying.

Hi,

can you please upload the dwg-file?

I would first check if the polyline is really exact on that wall, I would also try to first set the UCS manually to the wall and then start _PRESSPULL or _EXTRUDE and then using _SUBTRACT.

I had the same problem, when I tried to, resize a wall for the windows to fit, so I did it more barbaric, by exploding all the textures and remaking the whole wall with extrude with, with small extruded lines to fit the window...

Hi,

your wall is not a solid, these are 2 objects of type "Region" ... to use _SUBTRACT or _PRESSPULL and get the new object subtracted from an existing object the existing object has to be of type "3D-Solid"

Recreate that wall as 3D-Solid, then all will work well! 😉

Also take care with your wall, there are a lot created as region and as surface, sometimes region AND solids for just one side of the wall, you might run into troubles with that structure.

I tried to modify all of them to surfaces but it seems the problem still persists, I don't really want to recreate all from scratch

Hi,

>> I tried to modify all of them to surfaces

No, you should create 3D-Solids for your walls, not surfaces.

Remade the wall from parts, dunno why but if I try with polyline to draw a singer figure and extrude, it doesn't let me, I tried also converting them to 3d objects, still doesn't work... only to surfaces... Do you have any advice how can I do them maybe without splitting them into so many small figures, to create a bigger one, like how can I convert or redraw the wall without using so many small figures to assamble them into a bigger figure?

Hi,

>> converting them to 3d objects,

In your screenshot I can see that your wall is not just one 3D-Solid, but it again contains surfaces:

Also it does not make sense to split a wall into single peaces (as you seem to have according to your screenshot)

Please find this short video to see how to

• remove the existing vertical regions
• create one wall from the top region (you need then to use _SUBTRACT to open the wall for the doors)
• close the polyline you want to make a hole in the wall (it is not closed)
• then extrude this polyline
• then _SUBTRACT that polyline from the wall
