Make a drawing

Create a drawing from a part in Comiror: choose the sheet, place the views, add dimensions, publish the PDF and update it when the part changes.

The drawing tool produces a manufacturing drawing from a file already uploaded to Comiror, without CAD software. The drawing becomes a file in its own right, stored next to its part: it has its versions, and is shared and signed like any other file.

What you can make a drawing from

Not every file gives the same drawing. The richer the source, the richer the drawing can be:

File What the drawing allows Limits
STEP, IGES All views, full and half sections, centerlines, diameter dimensions, the parts list of an assembly None
STL, GLB (mesh) Views, shapes and overall size, dimensioned No section, no centerline, no reliable diameter dimension
DXF, DWG (2D drawing) The linework placed on your sheet, dimensioned and annotated A single view; no section, no shaded rendering, no parts list

For the manufacturing drawing of a part with curved surfaces, start from a STEP or IGES file: on a mesh, a hole is a polygon, not a circle.

Creating the drawing

On the file, click Drawing. The button is also in the preview and in the file menu, from the folder. Choose the format (A4 to A0), the orientation and the sheet format, then Create and open the editor. The sheet opens blank, with its frame and title block drawn.

The sheet format is your organization’s if an administrator has designed one, otherwise the standard Comiror one. It carries your title block, your fields and your logo.

Placing the views

The toolbar at the bottom of the editor holds the sheet tools:

  • Views: add the standard views (front, top, side, isometric) or a view in the orientation of your choice. Arrange in standard layout aligns them in first-angle projection.
  • Section: draw a full or half section through a view.
  • Detail view: circle an area to enlarge it separately.

Click a view to set it up in the right-hand panel: scale, rendering (Visible edges, Visible and hidden edges or Shaded), rotation of the drawing on the sheet. Views of the same projection share their scale so they stay in correspondence. The scale is picked from the ISO 5455 series, or as a custom ratio (Custom ratio…) when the part fits none of them: the ratio is then written under the view.

Dimensioning

With the Dimension tool, click an edge, a hole or two faces: the right dimension is placed (distance, angle, diameter, radius). Ordinate mode gives cumulative dimensions from an origin.

On a selected view, Dimension automatically places in one go what can be measured without judgment calls: the overall size, diameters and radii grouped by family ("4× Ø18"), the center distances of aligned holes. The rest of a dimensioning scheme says how the part will be machined and inspected: it stays in your hands. When the function holds back, it says why. Placed dimensions move and can be removed like any other.

The Symbol, Balloon, Annotate and Hole table tools complete the sheet: geometric tolerances, datums, surface finish, welds, part balloons and notes. For balloons and the parts list, see the guide Balloons and parts list.

Saving and publishing

Your work is saved as you go in a draft: the "Draft saved" indicator confirms it. One person edits a drawing at a time; others see it read-only while they hold it.

Publish turns the draft into a version that can be viewed, downloaded as a PDF and signed. You can enter the subject of the change: it prints on the revision line if your sheet format carries a revision table. The revision letter (A, B…) and the date go into the title block. A dimension that can’t be drawn blocks publishing: it is marked "?" on the sheet and listed in the panel, so you can fix it.

Each publication creates a new version of the drawing, which starts with no status: an approved or signed drawing that you republish needs to be approved or signed again. The signature of the previous revision stays attached to its version.

The drawing comes out as a PDF. It doesn’t export to DWG or DXF. Sheets run from A4 to A0 and views follow the European method (first-angle projection): American sheet sizes and projection (ANSI, third-angle) are not available.

When the part changes

The drawing stays linked to the part it comes from. When the part gets a new version, the drawing says so, and Update the views reprojects them into your draft: you decide when. Dimensions reattach to the new geometry when their attachment point is found again; those that aren’t are flagged for review, never deleted. The published drawing stays the previous one until you publish again.

To draw another part while keeping the sheet, the title block and the layout, use Change the drawing’s part in the sheet settings.

Getting the drawing signed

A published drawing is signed like an uploaded PDF: see the guide Approve and sign a drawing. The approval box in the title block stays empty until the signature.

Sending the drawing

A published drawing is shared like any Comiror file, with the rights you choose for each recipient: see the guide Share a file by link. If it needs approval, the signature is requested from the drawing itself.

Which plan

Drawing is included in every plan, Free included: sheets, views, sections, dimensions and symbols. The Free plan uses the built-in sheet format, ISO 7200 title block included; paid plans let you compose your own, with no limit on their number. Details are on the Pricing page.
