AutoCAD 2010 :: Subtracting Solids In 3D Modeling
Dec 17, 2012
I am beginner at 3D modeling, I have to solids and trying to subtract them. I have done it many time on this particular drawing but for some reason it is not working now. Here is my command prompt
Command: _subtract Select solids, surfaces, and regions to subtract from ..
Select objects: 1 found
Select objects:
Select solids, surfaces, and regions to subtract ..
Select objects: 1 found
Select objects:
Dimension disassociated.
Here is an image of what I need to subtract. Why is it not working?

I have some elliptical solids that were created using the 'loft' command. there are several that form a 'draft tube'. Basically, it is an upside down funnel that bends.
Anyways, I cannot get the sections of the draft tube to union. Also, Autocad will not subtract most of the draft tube solids from the building solid.

I have created the attached wheel drawing using the Revolve command.
You will see one cylinder solid thru the wheel on the attached drawing file.
I am trying to use the Subtract command to remove a hole space thru the wheel. Can't get that to work.

I'm using 2D wireframe as my default view while extruding some solid pipes. Everything appears to work fine, but when I switch to any other shademode eg. 3D wireframe, some of the pipes disappear. In Navisworks they show up as listed objects in the selection tree but cannot be displayed and more imporantly do not get considered in clash detection.
I can't see anything different about the properties of the "hidden" pipes over any others that can be seen.
If I slice the "hidden" solids, then one half or both halves become visible like a normal solid again.
I have hundreds of pipes to model and clash so need to resolve what's happening here. Attached is a small sample file.

I have an assembly with some hidden solids in which are turned to invisible in both part and assembly but they show on the drawing.
how to not show these in the drawing but still show the unhidden soild.

Is there a way in Autocad to create a solid that moves, for instance I have a piece of equipment on a hinge and i wanted to show how the equipment looks in use and then how the equipment looks once it moves on the hinge.

I have noticed that "Data Extraction" does not give you geometry information of a 3D solid such as position X, Y, and Z, and Length, Width, and Height. This information IS available in "Properties". Is there a way to extract this info to csv or some other format?

how I can Identify invalid solids without having to select each solid individually.I would think that a lisp routine would be the way to go, but I cannot find what makes a solid invalid as opposed to being valid.

AutoDesk 2014 . I am currently trying to design in iphone case. So I downloaded a replica iPhone from grab cad:
[URL]
I imported it and formed a solid around it, now I am trying to subtract the phone from the solid so it perfectly fits within the case. It will not let me subtract it though because the phone is a reference block and the square around it is a solid.

I have a solid that was created by extruding a regioned profile. I have made a lofted item (Yellow), that I will have to subtract from the solid (Green) to create a hole. When using the subtract command, I recieve the following error.
"The selected surface was ignored. Surfaces cannot be subtracted from solids or regions. At least two solids, surfaces, or coplanar regions must be selected."
I have tried convtosolid as well & to no avail.

I've created a list and want to subtract all the values within it from another variable, and assign it to a new variable. How do I do it?
Basically, I ask for ground level (assigned to variable G1), and then any number of depths beneath that (assign to list LVLLIST), and I want to return the value of the bottom point. So it's all the values in LVLLIST added together and subtracted from G1. And assign it to a new variable BASE.
For example,
G1 = 650.00
LVLLIST = (1.23 23.26 0.13 50.23)
(setq BASE (- G1 LVLLLIST))

I have been asked to make the title text larger (drawing are being issued at 1/2 scale, A1 to A3) on a large set of drawings. My solution was to copy the title attribute block to a temporary location, resize the attributes and redefine the block by running a script (scriptpro). Some drawings needed the title line split to next line so I had to move the sheet counter (1 of xx, 2 of xx etc.) which was linked to drawing file name for number with a field/formula.
The diesel expression shown below extracts that number. My problem is I cant figure out how to I can edit this expression to allow for a set not starting at 1. I had used a formula to subtract the difference,but how do you express this to run in a script?
This is my script......

When adding/subtracting from an existing selection I often use the wrong option in the selection module in the tool bar. I understand the theory behind the selection process in principal. However, I often end up doing the opposite. Any technique to add/subtract from an existing selection that is more effective than using the instructions suggested by the software help menu.

I'm trying to figure out a way to reduce the size of a cylinder that is created in another program (LFM or Cyclone) and imported into Autocad. I've tried Solidedit and I can increase the cylinder diameter but I can't reduce the cylinder diameter.

I have some round PNG icons where the pixels are either fully opaque or fully transparent. They look fine on a white background but are no use on a dark background.
E.g. see the orange icon attached. Ideally, the edge of the round icon would be semi-transparent orange so that it would merge nicely into either a light or dark background.
So, is there any tool in the GIMP that can correct the feathering? I.e. subtract the white from the pixels to leave a semi-transparent orange.
I.e. convert...
pure-white -> fully-transparent
light-orange -> semi-transparent fully saturated orange
fully saturated orange -> leave unchanged

I am trying to add some texture to some text by subtracting a grunge pattern from it. I've expanded the appearance of the text, so it is now shapes. However, when I place the texture shape over it and try to subtract it from the letter shapes, it only leaves me with the first letter.
Is there another way to do something like this? I would rather not have to keep subtracting the pattern from each letter individually. I've tried ungrouping the letters, then uniting them in the Paths panel, but it doesn't seem to be working either.

I am trying to find the interior volume of an assembly (when am I not?!?!) by subtracting the assembly from a block that surrounds the most of it. Somewhere the assembly has a "leak" and I have been trying to use the Cross Section Analysis to track down where the inside lump is connected to the outside lump to be subtracted. Is there a less time consuming way to dynamically drag a plane across and get cross sectional views?
Even better is there a simple way to animate the analysis plane moving across the block so I can hopefully just watch and pause it when I find a leak?

I am a bit new at 3D drawings, for many years it's been only 2D files used for .dxf purposes. My method is using "3D face" and them "extruding" to the size I want. When I view my layout or model, my 3D objects appear to be solids, but show some transparency. When I preview or print, they only come out as lines. How can I make these objects solid and print them?

I'm trying to understand extrusion to 3D solids better. This started when I drew a joined, closed 3dpolyline and found it wouldn't extrude (the shape titled 3D POLYLINES 4 sides joined, in the attached DWG), even though everything lies in the same plane (z=0). It gives the error "segment chord not perpendicular to normal". A chord is part of a circle, and there are no circles in the .dwg, so I don't understand the error. If you join only 2 or 0 sides, then at least 2D extrusion to a surface is allowed, but not if all 4 sides are joined, i.e. one 3D polyline.
If I draw regular polylines overtop the 3D polylines, then join and close them, it extrudes into a solid. This suggests that 3D polylines can't be extruded into a solid when regular polylines can, yet if I draw some scratch 3D polyline geometry that is joined and closed, these 3D polylines will join. It's as if I've found some secret shape that AutoCAD refuses to allow extrusion on.

As CAD administrator at my company, which is in the process of implementing Inventor/Vault, I am quite sold on the Layout Modeling/Multi-body part modeling functionality that Inventor supports. Among other things I believe there is a large payoff in assembly stability and simplicity. However, this workflow is very different from the conventional methods of modeling individual parts and manually constraining assemblies. URLs....

I've been trying to convert 3D dwg models to 3D dgn models without success, using AutoCAD 2012.
The DGN either displays the solid, which isn't visible in a Microstation extraction or it just exports the centrelines/linework and not the solids.
Is this possible in newer version ? i.e. 2013/2014.
I've tried the export to ACIS .sat file and that works fine, but it moves everything to the same lavel/layer which defeats to object of seperatng the items in the first place.
