Want to subtract one from other, but can't select the object

[ohyahta]

Hi,

I am using Autocad 2013.

 

I imported two solid models( *.stp) in one workplace.

(Drafting & annotation/insert/import)

 

I am trying to subtract one from another, But one is hidden from another.

(smaller one is in the bigger one)

To subtract smaller one from bigger one, I need to select small hidden one.

 

1. Anybody know how to select the hidden part?

I cannot see from outside.

 

If I have tree view(navigation??), I could simply select one on the tree, But I don't know how to make to pop it up.

Instead of clicking icons, I tried to use command, but I have no idea what each model name is.

(I tried imported file name, but didn't work)

 

2. would you let me know how to check the model name so that I can use in command?

 

3. When I use command, I put SUBTRACT - enter , (select object- actually I click on the object)

then it shows me "select objects:1 found"

but when I hit ENTER, it shows me "no solid, surfaces, or regions selected"

How can I properly select the object?

 

I currently imported two STEP files in one workplace, both are solid.

I am working on 3D modeling-solid editing-subtract.

 

Thank you!

Apparently AutoCAD does not share your view that the object you clicked on was a solid.

 

Click on the object again and check your Properties palette. What does it say. Or do a "List" on the object.

 

Maybe it would help if both objects were on different layers that used different colors.

I currently imported two STEP files in one workplace, both are solid.

 

I will assume that you have in fact verified that both are LIsted as solid bodies.

The problem then boils down to a select-other problem.

 

Go to wireframe shademode.

Select an edge of the first part Enter

Select an edge of the second part Enter.

 

Does this work?

No?

Then time to attach the file here.

All are same except file name in Misc

( I selected object / right click / property)

 

How can I fix this?

[ohyahta]

I tried wireframe, yes it is highlighted on each object, but still cannot select for the "subtract"

 

I want to attach files(*.stp) but it keep saying invalid file-

[JD Mather]

You are showing blocks not solids?

Explode each block once.

 

You said you had solids, but apparently don't know how to verify that statement.

Type LIst and select.

It should say 3DSOLID.

 

 

You can attach a STEP file here (if it is small enough) by,

right clicking on the file and select Send to Compressed (zipped) Folder.

Attach the resulting *.zip file here.

Yay!

 

I checked my models in Inventor, it said those are solids, so I thought so.

 

What I did was, type EXPLODE on each model then type LIST to check it those are solid model (it was "block") then type SUBTRACT, I could select!

 

Thank you so much!

Why didn't you do the subtract (Combine-Cut) in Inventor?

[ohyahta]

I don't know how to import two files in one workplace,

Actually I tried to "add new component" but, one appears far away from another,

I don;t know how to match the coordinates.

(Would you let me know?)

 

On the other hand, in Autocad, when I import two files, one is exactly in the right position.

 

Thank you!

That is not Inventor - that is Inventor conFusion.
