Isometric Drawing — VektorCAD Tutorial

This tutorial shows how to create a clean isometric pictorial in VektorCAD using standard tools. We’ll keep Normal thickness for construction/projection/dimensions and switch to Thick for final visible edges. Hidden edges use Hidden linetype with Normal thickness; centerlines use Center linetype.

We’ll draw the Isometric projection for the below drawing.

Step‑by‑Step

1) Setup

  1. Thickness → Normal (Thin / Normal / Thick).
  2. Entity Snap ON (Endpoint, Midpoint, Center recommended).
  3. Isometric ON, Turn Isometric mode ON in status bar and select ISO Left to begin.

2) Draw the left face

  1. Using Line command, start at the bottom corner.
  2. Enter @50<0, @20<0, @20<0, @15<90, @90<180, c to draw the left side rectangle.

Block

  1. Draw Line command and choose the end snap at 50mm and draw a vertical line to cut the top edge.
  2. Repeat Line command and choose the end snap at 70mm and draw a vertical line to cut the top edge.
  3. Repeat Line command and start at the bottom corner.
  4. Enter @70<90, @15<0, @70<270 and enter to create the L shape left face.
  5. Use Trim command to trim the intersection lines.

3) Draw the top face

  1. Change iso plane to ISO Top in the status bar.
  2. Turn Snap OFF and turn Entity Snap ON
  3. Choose Line command and pick the end point in L inner corner.
  4. Enter @60<90, @75<0 and pick the end of L to draw the top face.
  5. Draw the other faces as in the below figure.

  1. Copy the lines to finish the top faces.

4) Draw the right side

  1. Change iso plane to ISO Top in the status bar.
  2. Copy the line at the inner corner of L
  3. Specify base point at the corner and for second point, enter @35<90
  4. Copy the vertical line, inner edge of L
  5. Specify base point at the corner and for second point, enter @30<0
  6. Select both new lines and change the line thickness to Normal and Chain Stroke Block
  7. Click Ellipse menu in Circle dropdown menu.
  8. Click IsoCircle to draw isometeric circle.
  9. Pick the intersection point of the above lines.
  10. Enter 15 for the radius.
  11. Use Trim command to trim the top semi circle.
  12. Draw lines connecting the end of the semi circle.
  13. Copy the semi circles and lines and trim the extensions.

7) Add dimensions

  1. Dimensions (keep Thickness → Normal):
  2. Click Aligned dimension in Dimension submenu.
  3. Draw the necessary dimensions.
  4. Use Oblique command in Dimension submenu and align dimensions to isometric views.
  5. Select the dimension and enter 30 or -30 to align with the views.

Commands Recap

  • line — isometric edges and axes (@len<angle).
  • point — mark origins/centers if needed.
  • ellipse (Isocircle) — isometric circle for holes/bosses (Ø).
  • dimalign, — aligned dimensions.
  • Format panel — set Thickness (Normal/Thick) and Linetype (Continuous/Hidden/Center).
  • Status bar — Entity Snap, Isometric.

You’ve completed an isometric drawing with correct axes, line weights and readable dimensions. Export to PDF and verify line weights and scale in print preview.
