How to import a DWG into Vectorworks

Step 1 — Open the Import DXF/DWG dialog

With your Vectorworks file open, go to File > Import > Import DXF/DWG (or Single File) and select the downloaded DWG. The import options dialog appears before anything lands on the page; this is where every scaling and mapping decision is made, so work through it rather than accepting defaults blindly.

If you are bringing the block into an existing project, importing into the current document keeps it alongside your work. If you want to inspect it first, you can import into a new blank document and copy across only the geometry you need.

Step 2 — Set the units and scale

In the import options, find the scaling and units section. Tell Vectorworks the DWG's drawing units — millimetres for the metric blocks here — so it converts the geometry to your document units correctly. There is usually an option to scale the import to a specific factor or to match the file's stored units; the safest choice is to honour the DWG units so a 600 mm element imports as 600 mm.

Getting this right means the block lands at real-world size and you never have to guess at a Scale command afterwards. If the document is set to feet and inches, Vectorworks still converts cleanly as long as it knows the source is in millimetres.

Step 3 — Map layers to design layers and classes

This is the step unique to Vectorworks. AutoCAD layers can be mapped either onto Vectorworks design layers or onto classes, and the dialog lets you choose. For a furniture block, mapping AutoCAD layers to classes is usually best, because classes control graphic attributes and visibility while design layers control physical level — and a single block belongs on one level but may carry several attribute classes.

Review the mapping list before clicking import. Sensible mapping now means the block's outline, hatching and any annotation arrive on classes you can switch on and off, instead of a tangle of imported layer names cluttering your navigation palette.

Step 4 — Place and check the imported geometry

After import the block appears in the active design layer. Select it and confirm the size against a known dimension — drop a quick tape measure across the seat width, for instance, to verify the units converted correctly. Move it onto the correct design layer if it landed elsewhere, and assign its parts to your intended classes if the mapping needs a tweak.

Imported AutoCAD blocks often arrive grouped. You can keep the group for easy selection or ungroup it to edit individual lines. For a 2D plan block you usually keep it grouped until you decide to convert it into a symbol.

Step 5 — Convert the block into a Vectorworks symbol

To reuse the block, turn it into a symbol. Select the geometry and use Modify > Create Symbol, give it a name, set the insertion point, and store it in the Resource Manager. The block now lives in your resources and can be placed anywhere with the symbol insertion tool, with every instance linked to one definition you can edit centrally.

Symbols are the Vectorworks equivalent of AutoCAD blocks, so this step restores the efficient 'place once, update everywhere' behaviour you had in the original DWG, now inside a Vectorworks-native object.

Pitfalls when moving DWG blocks into Vectorworks

The classic failure is scale, caused by the wrong source-unit setting in the import dialog; the fix is to re-import with the DWG units declared as millimetres rather than to scale geometry by hand. The second is messy class and layer mapping that buries the block under dozens of imported layer names — take a minute over the mapping list to avoid it.

Watch also for hatches and fills: AutoCAD pattern hatches may not translate one-for-one and can come in as plain lines, so check any filled areas and re-apply a Vectorworks fill if needed. For clean line-based furniture blocks this is rarely an issue, but it matters on detailed symbols.

Finally, do the import setup once and save it. Vectorworks lets you store import settings so the next DWG comes in with the same units and class mapping automatically, which is a real time-saver when you bring in a whole library of blocks rather than a single file. A saved preset means every block lands consistently without re-deciding the options each time.
