filling in holes

 From: mickelsen 31 Mar 2011  (1 of 10)
 I created a drawing of a rail with a slider on it. I created the slider as a solid and then put four holes in it using boolean diff. Everything looked fine so I saved the drawing. I now realize that the holes are wrong. If they needed to be bigger, I would just use another diff operation, but they need to be smaller. I wish I could just "undo" the operations and make the holes disappear, but since I've done a save, I can't. Is there a way remove or "fill in" the holes so I can start over without having to recreate the slider from scratch? I've included the drawing so you can see what I'm talking about. Thanks, Mark Attachments:

 4161.2 In reply to 4161.1 For erase a the holes Select the inner surfaces, erase them, then erase circle top, and circle down on the surface You have erase the vertical hole ;) PS Take the habit to draw at the same scale than the grid, it's very difficult to manipulate something flying on the faraway free 3D space ;) Little trick of selection Select one inner face, you can now make a rectangle box selection, left to right for select all faces inside the box selection : erase them then make the same with a circle, you can now make a rectangle box selection, left to right for select all circles inside the box selection, erase them That all maybe 2 seconds EDITED: 31 Mar 2011 by PILOU

 4161.3 In reply to 4161.2 I am unable to select the inner surfaces. Whenever I try, it just selects the whole solid. What do I do now?

 Just double click on an inner face, or click one time and reclick one time on an inner face! Then use a selection Box left to the right! EDITED: 31 Mar 2011 by PILOU

 4161.6 In reply to 4161.5 I did solve my problem finally, with your help, but I wasn't able to get "loft" to work that way for me. I ended up drawing rectangles over the open areas, using "planar" to make them surfaces, and then "union" to use them to seal up the holes. I could then cut the new holes using "diff". BTW, the part looks great now but I wonder if the database for it is a mess because of all the operations that I've had to go through to get where I'm finally at. Thanks, Mark

 MoI doesn't have a database as such. Your model is what it is now. MoI's not history based like Solidworks.
