mark chng Posted February 2, 2005 Share Posted February 2, 2005 Hi Folks We have a model which is a box model 50x50x25, with a through hole in the middle. We plan to scale this whole object by 50% and yet still keep the through hole intact. Please advise if anyone has the solution. Thank you very much for all your help. cheers mark Quote Link to comment Share on other sites More sharing options...
Mike Twining Posted February 2, 2005 Share Posted February 2, 2005 (edited) Do you mean you want to keep the thru hole the same diameter (no scaling)? If that is the case, your hole needs to be an "Assemble Feature" not just a regular feature of the part. Otherwise, the whole thig will scale together. One quick way to scale a part by 50% (in my opinion... there are many ways to scale things) would be the following: 1. Assemble everything you want to scale in one assembly 2. Right-Click the assembly, choose "Assembly Properties" 3. Select the "Sizebox" tab. 4. Select all the check boxes under the "Display" section (see the Lengh, width, and height handles). 5. Make sure the "Aspect Lock" is set to "All" (same tab). 6. Hit "OK" 7. Right-Click on one of the handles that now appears at the Assembly level and choose "edit sizebox". 8. Take whatever number is in there and tack on a "*1.5" and you are good to go. MikeT Edited February 2, 2005 by Mike Twining Quote Link to comment Share on other sites More sharing options...
Robert Andersson Posted February 2, 2005 Share Posted February 2, 2005 Thats a very good tip, Mike. -While on scale'ing, sometimes it can be needed to use the command: (part selected) Shape\Reset Sizebox -On some imported then booleaned parts, Combine can be needed in some cases, if the scalecommand dont do the job. RM the part, Combine. Quote Link to comment Share on other sites More sharing options...
tlehnhaeuser Posted February 2, 2005 Share Posted February 2, 2005 Also,If its a box with a hole in the center. Then maybe its time to implement IronCAD expressions (parameters) and incorporate parametrics into the model. Quote Link to comment Share on other sites More sharing options...
mark chng Posted February 3, 2005 Author Share Posted February 3, 2005 Hi All Thanks alot for your input, is there such a basic commmand like a "Scale 3D or a Scale 2D"? The reason is because customer feel that they might want to just scale everything and sometime there is shelling problem when you do that. Just like any scale command, they are not so concern about if the shell size will change or not but just scale to meet their target model. Please advise..much appreciated.

mmccall Posted February 4, 2005 Share Posted February 4, 2005 I changed the base cross section of the feature and constrained the inner sketch with dimensions That will lock its length and width to a constant distance from the sides. Notice... only 1 feature is needed Hope this is what you were looking for... let me know. NEW_Sample.ics Quote Link to comment Share on other sites More sharing options...
mark chng Posted February 4, 2005 Author Share Posted February 4, 2005 Thank you for all your support My customer has many parts previously drawn and would like to just scale every part together using "1D scale" if there is such. I have attached a image and hope that will explain what i mean. Appreciate all your help.

Mike Twining Posted February 4, 2005 Share Posted February 4, 2005 You can get close to that result by simply following the directions I gave you above, but make sure you have your "Aspect Lock" set to none. Grab the handle in the direction that you want to stretch and tack on your scale factor. You won't end up with oval holes though, as those features are not "scaled" per say, but now fundamentally different (hole does not = elipse). So, for your particular example, you would then need to go back and address the holes individually (hopefully you have them all "linked" together so you only need to edit 1). Hope this helps.

Robert Andersson Posted February 5, 2005 Share Posted February 5, 2005 Actually, you can get the holes to scale. -In the crossection, RM a circle/ Prop/ UNcheck Circle. Leave the dims as is. Quote Link to comment Share on other sites More sharing options...
