    <description>&lt;P&gt;One of the first issues to address in creating a geometric CAD model is how will the model be used.&amp;nbsp; Do you need a precise and accurate representation of a curve becuse you intend to use it to produce machining instructions or perhaps a 3D model to determine potential interference between parts of an assembly or maybe your final output will be a photrealistic image or animation.&amp;nbsp; For the latter, CAD systems conside &lt;A href="https://en.wikipedia.org/wiki/Level_of_detail_(computer_graphics)" target="_blank" rel="noopener"&gt;Level Of Detail (LOD)&lt;/A&gt;&amp;nbsp; that automatially adjust the how much detaill is calculated and displayed as a function of the distance of the focus of interest as a function of the distance from the viewing camera.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;What are the uses for your CAD model?&amp;nbsp; What will be the final output that will be provided and used by the end user?&amp;nbsp; Back in the days of manual drafting bolt threads were drawn to show each thread at the correct size and pitch.&amp;nbsp; This detail was often replaced by just a centerline and a note of the thread size and type.&amp;nbsp; In general, you should only provide enough detail that wil be needed by the end application.&amp;nbsp;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;AutoCAD 2019&lt;/P&gt;&lt;P&gt;I have a piece of equipment that is very large in file size, 35.5MB, just on its own. This DWG has only 3D solids in it (about 2k) and each piece is represented, like nuts, bolts, and washers - even the voids within pipes.&lt;/P&gt;&lt;P&gt;My goal is to make a single 3D solid that does not have shared surfaces, I don't want to see the outline of the threaded bolt or pipes ID wall when in 2D wireframe - just a shell of the overall equipment and depressious of where a connection would be. I am hoping this will make the DWG small enough to later make it into a block that can be used in our main drawing without causing lag issues and excessive lines in a plan view.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I have done/tried the following:&lt;/P&gt;&lt;P&gt;All general properties set to BYLAYER/COLOR&lt;/P&gt;&lt;P&gt;PURGE &amp;amp; -PU REGAPPS&lt;/P&gt;&lt;P&gt;SOLIDEDIT&amp;gt;BODY&amp;gt;CLEAN&lt;/P&gt;&lt;P&gt;SOLIDEDIT&amp;gt;BODY&amp;gt;SHELL (thought it would just make a skin over it all...nope)&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I cannot share the actual file for NDA purposes, but I have attached a DWG for one of the connections to show an example of what I have.&lt;/P&gt;</description>

      <description>&lt;P&gt;You could use 3D modeling commands such as Patch (surfaces) and Sculpt but those would be tedious and by themselves will not solve your issue - the components have an excessive amount of detail which unless "required" to be there, should be eliminated.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;One such example is the valve - the flutes make for great eye candy. In the pic below, at left is the original valve, the middle shows the interior voids filled and at the right, a valve without flutes and interior voids. If you equipment is much larger than the example valve, seriously, how important is it to show flutes on the valve (or fillets on the hex nuts, the split of a lock washer, each step offset on the valve)?&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Washingtonn_0-1653161284542.png" style="width: 600px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1070248i77A82338F07BB22C/image-size/medium?v=v2&amp;amp;px=400" role="button" title="Washingtonn_0-1653161284542.png" alt="Washingtonn_0-1653161284542.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Washingtonn_2-1653162108262.png" style="width: 600px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1070254iB3E21D11B8F6A5D0/image-size/medium?v=v2&amp;amp;px=400" role="button" title="Washingtonn_2-1653162108262.png" alt="Washingtonn_2-1653162108262.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;The resulting drawing size for simplified valve version (right side) is reduced by 39% over the original (left side)&amp;nbsp; version of the valve. Although the middle shows an increase over the original, this was a result of combining solids and then filling the resulting solid voids.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;The equipment is (in our case) to be used to connect our two duct lines, but the plumbers also need to connect to it and see where their connections are, otherwise Id normally just make a 3Dsolid box for it; we don't need it to show the internal piping and structure.&lt;/P&gt;</description>

      <description>&lt;P&gt;A high level of detail is not needed, what you have on the far right is what would be preferred if not even less detailed than that. The overall equipment has about 30 connection points and, even though our duct only uses 2 of them, the plumbers will need to know where to have their connections. I only need a shell of the valve, no internals are needed. How did you fill the void and clean it up?&lt;/P&gt;</description>

      <description>&lt;P&gt;The middle version was filled in as previously indicated using PATCH and SCULPT commands, the right hand version was created using the original as a guide and running a polyline around half of the cylindrical portions, revolving&amp;nbsp; about the centerline to create a solid and the using UNION to add the non-symetrical parts of the original valve.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;The whole point is to only provide the detail needed to get he job done at the start so you don't have to jump through hoops later.&lt;/P&gt;</description>

      <description>&lt;P&gt;I was afraid of that. I wish I could simplify these parts quickly but does sound like it would be a long process to basically re-model all of the connections. Was hoping that filling in the solid would lead to those interior lines being removed or a way to make a separate skin of only the outside. I was able to clean it up some with the SOLIDEDIT and clean but still leaves a lot of lines. For now, we have decided to make a separate file with only the equipment in so we can keep the main file size down and just XREF in to the main as needed.&lt;/P&gt;&lt;P&gt;Your method for the right hand version would indeed be the way to go though if I had the time to do it; Ill need to do that in the future when work is slow and I have time to. Thanks!&amp;nbsp;&lt;/P&gt;</description>
